Halo - Ancient Human History - Lore and Theory 

The Hellcat armor in 5 is stated to be strangely familiar to humans. They know it means something to them but haven’t figured it out yet.

"Was this a lost colony?" "I dont fucking know"

I think in an episode of Halo Legends there was a scene where they come about ruins that wasn't forerunner and hinted to be Ancient Human.

Pretty sure ONI is fully, or atleast some what aware of ancient humanity

@@tragic_solitude7992 if those ruins and most of all those stairs in babysitter parts were made by ancient humans... Then they would be more bigger than 12 ft in average

@Mr.Tweezy007 where did you get that from? I mean, I'm not sure, but I thought humanity was originally from either earth or mars

Maybe their homeworld is Mars and it was bombed to a barren wasteland. After that, earth was the only habitable world and this is when humanity was reseeded on earth.

We are by far the most relentless pain in the ass for anyone and all that tries to gets rid of us.

@Mr.Tweezy007 Humanity is from earth, clearly stated in the Forerunner trilogy.

@@off_Planet Humanity is indeed from earth.

Rocky Balboa: I didn't hear the bell ring!

@@robinchwan Chosen Undead: Open your ears!

Humans are tenacious if nothing else. Not the greatest hunters or warriors, but the greatest survivors.

Basically to put it in perspective we Humans are like Cockroaches that just don't completely die out. We survive and build again. In Human perspective we are a Tower of Willpower and intelligence

@Dylan Jones But how exactly does sacrificing 1/3 of your population make you worthy? It's not even a good plan to begin with. If the idea was to inject a virus into the flood in order to "infect" the Flood, they should have only infected one planet, or one person. If the idea was to PLEASE the Primordials by sacrificing a 3rd of their population... that's a massive leap of faith. But they are also dwindling their reserves, just incase the Precursers decide to continue on with their genocide, even after they were offered the 1/3rd. I recon that most of Humanity didn't even agree or get a say on if this plan should be executed.

Yup basically

Humans are best known for their "No U" and "Go fuck yourself" moves towards any force that pushes them back, clearly gods chosen species. We are also very annoying

Ya’ll ever realize Uno reversed is No U. So like the reverse card is pretty much a “No U” card.

Martin XY lmao

Andrew Pandrew uno is just no u mixed up too

SelchDa117 And wiped out their own creators, hunting them down to a whole other galaxy in order to do so. Yeah they aren’t so friendly lol

Which is one of the reasons why the Precursors judged them to be unfit to carry the mantle.

SelchDa117 They’re pretty much mega advanced Nazi’s, if you think about it-

It's called genocide

SelchDa117 Yea when you think about it the Forerunners where kind of huge assholes.

The librarian said she imprinted the ideas in humanity to create everything about the chief and Cortana

Not in a good way tho

HHMMMMMMMMM

If they are, then Humanity has made a very bad asthetic to it.

In halo 5 it describes the hellcat armor (which uses technology from an ancient human ship) as 'utterly alien but strangely familiar'

then we cant relate because the technological advantage would be alien to us and there woulnt be much of a story

@@robertle7156 true

Technically they used human artifacts to make their technology. Humans would use gravity as a weapon.

@@nothuman3083 We don't know if the Covenant used Ancient human tech, they did reverse-engineer and adapt Forerunner tech though

@@ebimd1851 The whole "glassing" thing the Covenant loves doing is actually Ancient Human tech.

Damn raptor.

You can see when you look at her, she's working it out. They should all be destroyed!

Not really technically its the mantle gene hardwired in their DNA so they are technically flood. The flood once it achieved high brain power remembered it gave them the mantle and wanted the forerunners to pay for their sins. So once humans where devolved the forerunners took the mantle and implanted it in themselves. Flood returned and would just snap its tentacles and forerunners became flood

@@nothuman3083 where did u get that information from?

Donald Baird what he’s really trying to say is that the flood were precursors. They were so so intelligent that there technology is pretty much Incomprehensible. There technically is Made of neural physics in which the universe is a living being and that made them travel through the stars and explore the whole halo universe. The had a belief called the mantle of responsibility in which who ever held the mantle is in control of protecting the universe and life itself. Now to make everything short. They were going to give it to the forerunners but they proved unworthy and passed it to humanity. The forerunners killed the precursor out of anger and took the mantle for them selves. The surviving precursors turned them selves into a dust which millions of years later turned into the flood due to the corruption of the dust. So now they attack the humans but let em go and then attacked the forerunners for revenge for what happened millions of year ago.

You don't understand how much it would change in the Halo universe. It wouldn't be just one cutscene but a collection of the most advanced technology in the galaxy. Made by humans for humans.

I genuinely pray that in ancient humans somehow makes it into Halo 6 cuz I never even thought of 4Runner would be in a future Halo game and then look what happened

@@mafiaps31 the hellcat armour is a primitive (by comparison) recreation of ancient humanity's combat skin so there's that at least

www.halopedia.org/images/a/ad/Ancient_Human_cruiser.jpg Apparently an Ancient human starship design from Halo: Warfleet

@@ebimd1851 apparently thats the one ONI have captured...

Wow

Sounds like the stories my father told me

Makes you wonder how the Forerunners were able to defeat the Precursors if it took them 53 years with all of their military might available just to besiege a single Precursor structure.

@@Omega4Productions It was briefly touched upon in the Forerunner series by Greg Bear. Do you want me to tell you what happened? I don't want to spoil it if you don't want it spoiled.

@@AvalancheZ250 I've read the entire trilogy, but it has been a while since I've read them so my memory of them is fairly dicey. They're damn good books though. Anyway, point is, fire away. Would be nice to jog my memory of what happened anyway.

I doubt that. Only chief because she accelerated his evolution.

Not exactly, she planet the seeds but Chief is basically the part of the plan that “succeeded”

not quite, just accelerated us towards what we used to be in halo cannon

Spartans are just the second step of human evolution, and it took more than 40 milion years to become an ancient human, in just 5 milion years ape become human, I think Spartan need more than one steps to compete with the ancient human

Spartans are not even close to ancient humans

Imagine a movie portraying the human empire and their fall to flood. That'd be a damn good sci fi zombie movie.

@@hasturxix how would you pack hundreds of years of warfare and proceedings into a feature length movie though. Like, you could make an entire series about this.

@@Lrofmaulol Several Seasons of it really, Just the Human Forerunner and concurrent Human Flood War could take a whole Game of Thrones worth of episodes to do it all. Let along the Forerunner Flood war up to the activation of the halos could be another entire series altogether

A game in that ages would be amazin too

I've felt the same way about warhammer 30k that if they were to make a movie collection about that time it would be amazing same with this to have a collection of movies showing the human forunner war and the flood the building of the halo ring's it would have to be like the hobbit and the Lords of rings movies except it would be all six movies about this time in halos lore and each film would definitely have to be over three hours a piece but it would make one hell of a good watch. Unfortunately it would face the same problem as a warhammer 30k film collection it would have to be done by a good director and stay true to the lore something on that scale halo, 30k it could so easily be done badly think about what happened with the doomed movie they changed one thing in the story the removal of hell and demon's and because of that it ruined the movie and that's what I mean a movie about the human forunner war would have to stay true to the lore rather than trying to appeal to a larger audience which is what I think went wrong with the doom movie instead it should aim to please the fan base and if its done right then more than likely you would get none halo fans or people that know the games but not the lore so much enjoying it. Still though who knows maybe they will make a film in the future though I also agree with another comment made that a game based in this time would be pretty good as well in fact I'll settle for that for now lol

It's certainly possible. There was a spartan that got stuck in the 21st century for a time then went back to the 26th when the slipspace accident sorted itself out.

Theoretically possible, but the known factors of shifting along a temporal axis have only ever been recorded by as many as 7 days, and have yet to identify the cause(s) of why their primitive drives caused these shifts, when modern and covenant drives do not.

And here you highlight why i believe *George Is Alive*. Only moments will have passed for him since the slip space malfunction. It's not a stretch he'll spat back out. And even without a helmet he'd survive. Humans can survive for a several minutes in the vacuum of space.He's a spartan

What about the inverse?

That would be a different dimension or timeline.

Let's hope the "translated" name of ancient human weapons are not something super weird but strangely familiar, for example: Weeabo Assault Rifle.

You mean a reskinned magnum?

They were near it. Looks like democracy didn't exist that Life Time.

It’s just a theory, A GAME THEORY

If the Imperium never destroyed or outlawed any technology or made ang mistakes during the Great Crusade, then yes, it would be similar. It would be closer tech abd operations speaking to what the Emperor was trying to achieve.

Don't u mean Forrunners? Humanity seemed absorbant to xeno species and tech. Much unlike the Imperium and the Forrunners. Where a majority seem xenophobic to other races coexisting.

They were a more... xenophobic breed, or breeds, true, but it seems that the Mantle demanded a kind of dominance or superiority of its upholder. Which doesn’t explain why the Precursors themselves were culled... unless it was a ALL elements of a plan; humbling man to a more compassionate lot and simply removing the parent so the child can stand alone?

Dont worry, it is ongoing, right *now* , in the halo unvierse players know. But, one problem still, *Cortana...*

The forerunners were huuuge asshole destroyed a lot of ancient human tech. Requiem data was probably their best lead. The Hellcat armor in 5 is based off a recover ancient human suit. Which humans have notice it strangely familiar to them.

The surprise cutscene in Halo Reach ending States that it was the year 2589 37 years after the war ended so pretty sure by that point in the Halo story they are very close store I've already begun the reclamation

I think even under the best circumstances, it would take humanity circa 2558 several centuries to truly recover their ancient culture and technology. And it would take centuries after that to take the mantle. Ancient humanity was unbelievably advanced.

Ancient humans were far more generically evolved Than The Modern humans Any ancient human soldier can defeat the unsc Single handedly Imagine 14feet tall Gravity controlling Near invincible Humans Being compared To weak humans Of 2559

Let's be real mate, the deciding factor is the bias of the writer and how much plot armor you give.

True, especially considering the only, ONLY advantage Humanity had was in weapons tech because they could actually understand Precursor tech somewhat, unlike the Forerunners. The Flood had already severely-crippled their empire by the time they started fleeing to Forerunner border space. The Humans were trying to take more resources to make up for what they lost to the Flood. Since they were losing to the Flood abd neefed more worlds to fight them off and given Humanity's tech level, they would have lost at least 50% of their Empire to the Flood, and this is only the beginning of the Human-Forerunner war. By the late parts of it, Humanity had about 20K worlds in at least a thousand systems (and all the other natural resources in the space between) but it is not known if this was before or after they sacrificed a third of the remainder of their Empire to the Flood with countermeasures which kinda-worked, but were NOT a cure. They were designed to not give the Flood more biomass. The Flood then retreated on its own to preserve the Humans for the Precursors' plan and fool everyone into thinking there was a cure. But back to the main topic: Ancient Humans had 20-30 thousand worlds well into the Human-Forerunner War. And assuming that they lost at least 50% of their Empire to the Flood before moving to Forerunner territory, thst means they had, as a very conservative estimate, at least 60K worlds and whatever resources existed in the space between them before the Flood Happens. Yet by the time they fight the Forerunners, they are left with a crippled civilization and divided military trying to contain so many Flood outbreaks against over 3 million Forerunner worlds and their domain over the vast majority of the galaxy. That's being outnumbered at least 1000-1 by aliens more-advanced in tech and bio-engineering, supplemented with many times aa much automated assets like billions of warships the Forerunners could just throw at their problems, each carrying dozens to thousands of War sphinxes, each pair of which could merge and shatter continents. Ancient Humans fought off the Forerunners while constantly losing bit by bit for over a millennium, and that's AFTER the Didact used star-hopping to target only thr most-important Human worlds and cut or slow to evolutionary crawls all Human slipspace travel using casual reconciliation jamming. Then the Full might of the best of the best and most-powerful Forerunner forces battered thenselves useless again and again for 53 years on Charum Hakkor. A single Human world, devoid of any support, was able to resist countless and constant Forerunner attack for 53 years. By that time, the Ecumene was starting to seriously strain their economy fighting the supposedly-primitive and barbaric Humans. It is said in the books that the Human-Forerunner War weakened the Ecumene so much it was a considerable factor as to why the Ecumene was so unprepared for the Flood 10,000 years later.

A unified imperium of man with the emperor actively leading it would merely flick the ancient human empire from halo aside. However if the two ever hypothetically fought, the emperor would likely use his op bullshit plz nerf charisma and emperor magic to facilitate a unification between the imperium and the ancient human empire. (I know it seems like fanboyism that I say the imperium would swat aside the AHE, however a unified IoM has legions of adeptus astartes with their primarchs to lead. The imperium in this state fields LEGIONS of Adeptus Mechanicus TITANS with upwards of 1000 titans per legion. The only major advantages the AHE from halo would have over the imperium is, 1. Faster and easier to use FTL technology that can be used from inside a planets orbit if absolutely necessary to do so. 2. AI. Although the adeptus mechanicus wouldn't get as bat shit crazy about AI if the emperor could be convinced that the halo AI was stable. While the two advantages here are major advantages, I do not believe for a second that it would be enough to overcome the imperium of man being lead by the emperor.)

@@Benthesniperof8 Your forgetting that the ancient humans had weapons from studying precursor relics that surpassed by far even the forerunners weapons. Their ships could destroy planets in a single blast, whereas IoM requires special ordinance for Exterminatus. They also had combat skins which in the forerunner ranking goes from 1-18. Master Chiefs Mark VI MJOLNIR ranked a solid 2 on that scale, and rank 8 was recommended for fighting flood. The Didacts combat skin despite being a 100,000 years old and probably not his full armour was able to manipulate gravitational fields and crush MC to the ground. I don't know what their canon abilities will be since 343 made Forerunners quite a bit weaker than they were in the books, but going by ranking, the Ancient humans could have fought on the same level as Adeptus Astartes, and been a threat to Primarchs, their best advantage would be slip-space (no demons in transit), which is far faster allowing the forerunners almost instant travel, and for ancient humans not too far from that. They also had true AI as servitors, which far surpass the cyborgs in the Mechanicus. Their ships would simply overpower any IoM, even if they were somewhat equal on the ground due to Primarchs, the more powerful Astartes and Psychers and the difference in the number of troops the IoM can throw at an enemy to win. That said I agree they would almost certainly come up with a peace agreement. The IoM is extremely good at convincing people to worship the emperor, and only use violence and subjugation as the last resort. They would also provide a huge ally against Demons, Eldar, Orks, Tyranids, Necrons etc. If the Big E still has enough healthy cells they could probably revive him without heretical xeno tech as well. Basically the Imperium would win the galaxy by default.

Unless I overlooked it everyone missed one major option. The home field advantage question. Who is the invader in this fight between these two civilisations? The invader has limited resources while the defending side has everything that can be offered up in defense. Ancient humans defending would win without any doubt. IOM defending seems to have an 80 to 95 percent chance of winning if the attack comes from outside the current universe. If the attack was a massive fleet attack with ancient humans trying to take back Sol System and then hold it against invasion the tide of battle changes to an almost 50/50. The ancient humans would control space and the sky's above every world in the system. Once they have a base of operations and the ability to manufacture ships and weapons the entire battle becomes a siege. Trap a planet and take it or just wipe it out with a single attack. The IOM is going to have numbers as the only advantage in this type of attack. If arguments are made saying other races would be the difference maker in an ancient humans invasion of the IOM you also have to add the super advanced civilisations from Halo into the mix and the simple fact that they don't have any well known races that are weak and not possible of defending or attacking at the same or better level as the ancient humans the fight seems to overwhelmingly tilt in the favor of Halo. Remember that the IOM isn't well known for its ability to adapt and advance tech found in war. Ancient humans became the power they are based on the fact that they always pushed forward with new and better tech from more advanced civilisations.

Same. As well as the facial features.

They looks like aztecs/Mayans to me.

They never existed in the first place.

I want to know what Ancient Humanity powered armor are called thought (Forerunner powered armor are called Personal Armor while Forerunner combat-oriented powered armor are called Combat Skin).

Not much more to go on than this.

@@dasbubba841 imagine a USA vs. USSR approach to modern technology

Yeah I caught that as well. 50 years in the orbit and Charum Hakkor and 3 years on the ground (not to mention the years before spent fighting throughout the other planets in the same system, such as Sothra Hakkor). In the end, the Forerunners didn't even overpower humanity; they had to enlist the treason of the San Shyuum. That condemned every human and every loyal San Shyuum left on the planet. Even after Charum Hakkor fell, 40 Prime Cruisers and 10 First-Rate Tuned Platforms escaped and fought the last battle in a system with the wolf-faced planet. In their end, they burned every world in the system to deny the Forerunners the resources of that single, last system.

@@AvalancheZ250 it would've been really ironic if the present Day San Shyuum had recruited the Humans into the Covenant

What's your point

Same

It's about to be way more

By the 26th century Humanity has Essentially regained it's original biological makeup and is arguably the most Intelligent species in comparison to the other known species

Joshua Michael where is that ever said? It’s established that new humanity is still inferior to the older version. Weaker, smaller and lives shorter lives.

@@bluenight104 It's said right in the video. Generally they aren't as strong or big as ancient humans but even in real life we have people like Dwayne Johnson and LeBron James. Otherwise we're most likely just as smart as ancient humans and the Spartans are fully brought back to original human standards. The extended life spans were probably due to advanced biotech/medicine

Joshua Michael I must’ve missed that tidbit

What grounds your belief? I’m not criticising because I buy it too, but on what ground do you hold this belief?

Kind of, the Ancient Human ship that was long and had a tall prow is similar in shape to a Lantean/Alteran Aurora battleship, except smoother and with less exterior greeble, suggesting more external armor

If it had Ancient/Lantean drones, the Forerunners would have known fear.

@@JoaoPedro-gc8mw just imagine if Forruners had discovered oil

@@JoaoPedro-gc8mw well, the Didact said in Cryptum that "Humans, with the assistance if the San Shyuum, were able to create offensive technologies which my Promethean Forces had no defense against" which he says is part of the reason Humanity lasted so long against the Forerunners despite being exponentially-outnumbered. Given the tech level of Ancient Humanity, they vell well could have plausibly made such weapons easily.

@@fadelsukoco3092 I believe this was the Energy protector, which makes it a bit ironic that a bastardized was used to Glass human worlds.

Yeah probably a coincidence actually

Librarians did plant the seeds for us to return to our former glory. Through we have set back ourselves many times.

What you said is true

The Prometheans are the Necrons. The Ur-Didact is the Silent King. Both fire weapons that disintegrates their targets and are mechanized warriors driven by the shackled, digitized conciousness within.

I believe that they tried to do something like that, but the forerunners didn't believe humanity if I remember right.

It actually was flood landing on one of the forerunner worlds that caused humanity to glass it sparking the war as forerunners thought humanity was getting in a first strike to take the mantle unaware of the flood until after the human forerunner war when viewing humanity's archives to find out why they were assaulted

Primordial is actually Ctulhu

Considering that the forerunners seem to use hard light rather than plasma weapons, and the prophets were the allies of the ancient humans, something tells me there's quite a bit of irony in the weapons used to kill humans and glass our planets by the covenant.

Mark Mulder well given that the Forerunners were driven to a mad jealousy when Humanity were selected as heirs to the Mantle, to the point where they declared war on the Precursors in an attempt to claim the Mantle by force and in the time after that both the Precursors were eradicated from the galaxy and Humanity mysteriously entered a series of dark ages, causing them to lose the vast majority of their knowledge and technology... I guess we’ll never know because obviously they lost the records of it in the dark ages

At the moment in the halo universe, yeah, we're far from it. In our Ancient past, we fought both the Forerunners and the Flood, simultaneously, and held our own for 1000 years, until our fall. Its obvious that Humanity are makes ng steps back towards our ancient greatness. The Spartans are heralded as being exactly that. We will inevitably get there.

Well I know pretty much everything about Primarchs amp.reddit.com/r/40kLore/comments/619zbh/primarch_special_abilities/

Basudeb Sarkar Prometheans were a rate of warrior servants in Forerunner society that later became composed and turned into those machine like creatures we see in Halo 4 and 5. It’s stated that Prometheans armor were Tier 13 as opposed to Master Chiefs Tier 2 on the scale of forerunner power armor. Since the forerunners beat and that it’s been stated in the Greg Bear Halo novels that ancient humanity wasn’t quite as advanced as Forerunners we can assume that human warriors weren’t quite as powerful. Now onto Primarchs. Primarchs were able to single handedly conquer entire planets by themselves and not just earth like planets but straight up savage ass planets. Primarchs were almost unkillable in every aspect of the word and we’re basically on the level of Demi gods. Vulcan has the ability to cause earthquakes by hitting the ground and plenty other Primarchs have done shit like decapitate, lift or melt Titans with their strength and mind. No where does it say Promethean knights could do shit like this. At best Ancient Humanity are stronger then space marines but they ain’t Primarch level. Bruh the Didact got taken out by a grenade while Primarchs could have similar shit happen and brush it off.

I do as well! What was so bad that it caused people to off themselves?

Primordial: your mum

he probably just told them the exact details on how the forerunners smoked the precursors and how that led to the flood...prolly also told them it what if feels like when they turned into the flood
