Why did the Earth Before the Dinosaurs Look So Terrible? 

More oxygen = larger insects. I'm glad we don't have those today.

At 0:46 when talking about LUCA you show a multicellular creature, which it wasn't. At 2:40 you show an image of Theia striking the Earth head-on instead of the oblique hit necessary for the Moon to form. At 3:18 you note that the impact caused the Earth to tilt, but, rather than showing a tilted axis, you show the orbit of the Earth as extremely oblong as if seasonality had something to do with the distance from the Sun. At 3:29 you mention that tides may have influenced the beginning of life without explaining how. At 3:52 you say that carbon monoxide may have helped life start but you don't explain how. From 4:07 to 5:11 you misrepresent the panspermia hypothesis. You claim it says that life began from either chemical precursors or microorganisms delivered from space. This is false. It specifically refers to alien life (microorganisms), not chemical precursors. At 4:42 you refer to evidence of amino acids (chemical precursors) found in an asteroid to support the hypothesis. Amino acids are not life. You then conclude "Although it sounds like science fiction, it is a possibility". Anything is possible, but there isn't any evidence to support the speculation. You did it for dramatic purposes. I stopped watching at this point because I realized this was a sloppy and unscholarly effort designed more to attract viewers than to seriously explore science.

It's almost as if Earth is an egg that was fertilized.

If life comes from space, then I'm pretty sure we are not alone in the universe...

" Why did the earth look so terrible " ??????? These thumbnails are ?????

6:12 that whale definitely came from outer space 😂

Megalodon 108 meters!!! Try 20 or so (around 65 feet). Can you just imagine a shark 330 feet or so long. Yeah, nutzo.

even tho there are harsh conditions, these early periods were crucial in setting the stage for the development of life as we know

Ammonites became extinct at the end of the Cretaceous period, about 66 million years ago, at the same time as the dinosaurs.

Panspermia doesn't mean "we are all aliens", just that the building blocks of life could have originated outside the earth.

What If The Earth rotated twice as fast with a 12-hour day/night cycle or twice as slow with a 48-hour day/night cycle

Only thing we know for sure is that we know nothing.

If life is from the space, then where is the life in space from?

'Bone-headed' Dinosaur, huh??? Wow, we still have some 'Bone-headed Dinos' in this day and age. Whoddathunkit???

13:41 Seriously, who's naming these things?? LMAO!!!😂😂

Does anyone notice that when they explain life & and creation, it's basically speculative, but as soon as they start talking about the destruction of the dinosaurs, the explanations are exact and precise. We don't know much about how things get started, " but when it comes to complete annihilation and destruction," we got that all figured out folks !

Why hasn't any new "lifeforms" appeared from the "pools" of water across the planet today?

We came from the slime at the bottom of the ocean, we are earth Snott

And here we are thinking we're all that and a bag of chips, when we came from space worm proteins.

That rock came from somewhere. Wherever it came from has more life juice on it.

Are we talking about the Hallucigenia from Attack on Titan again??? 👀

Here's the real answer. We don't know and technology has made us think way too highly of ourselves.

Early Ai comparative size modern humans sure developed an odd animated shoulder swinging gait.

what a nice extended evolution documentary about life on Earth, thank you very much

Very old theory which has to be the only way the building blocks for life etc got here considering that Earth at one point was a ball of molten rock and therefore sterile when it cooled.

I'm fascinated by the oxidised earth after the GOE. It seems evolving Gigantism was in a "short" burst over millennia, It makes me wonder if even Earth's Gravity was lighter back then.

Was working on my family tree and greatly appreciate the information. Now I can say with confidence that I am a great grandson of LUCA. How far back does your family trees roots go?

I created the earth last Friday in my shed cos I was a bit bored, you're welcome.

What makes the theory of life from space a bit silly is the question as to how life would have formed in space while it allegedly could not form on a much more suitable planet earth. As to the theory of the "building blocks" coming from space, again: Why would they exist only up there, when everything that exists in this region of the galaxy also exists on earth? Also, Carbon and Nitrogen are very basic Elements, we have much rarer and heavier Elements such as Uranium and Gold that are also commonly found across planets and asteroids in our immediate neighbourhood.

Funny thing is ....Earth IS in "outter" space

Do the Math, us being alone is simply impossible. 2 trillion galaxies in the observable universe so far. Each contain an average of 500 too 800 billion stars. Most of those stars have moons and planets. So, we are not alone, it is simply ridiculous to think that.

i'm starting to think we were a freak accident. and shouldn't hold our breath about life on other planets. just look at all that had to happen before this planet could become habitual for us. and it won't remain this way for long

"You are most likely an alien" is unsupported hyper speculation.

And yet we so busy trying to kill each other.

When did the earth stop being bombarded by asteroids? Strange how that doesn’t happen anymore.

The Moon was dragged out of the earth, thats what gave the earth tectonic plates and thats also why its made from the same stuff

Back when mothra lived.

6:10 Bluewhale with two pectoral fins? Really? Now THAT'S an alien.

45:30 There was no Mediterranean Sea at that time.

Quite a few assumptions as to where life came from. We know of life's existence but not how of how it came to exist. Just admit it. We just don't know.

If you live somewhere for over a billion years, you're no longer an alien...

Title: before dinosaurs. Content: 3/4 dinosaurs

I kind of feel bad for the dinosaurs for what they went thru the day of impact.

“Instantly vaporized within minutes”

Did i miss how the water got on earth...

Nahhh its scary to live at this young earth where theres no phone ,clothes,😂fire, And you just see bunch of scary creature ahahahahahah i think in my first life i am a bacteria

Where do insects, like bees that pollenate plants, fit into the timeline of dinosaurs?

This planet has been seeded by otherworldly beings, after they took out the dinosaurs by tossing an asteroid to earth. Nuff said !!

Shouldn't the thickness of the lava be listed in cubits?

The key word is "believe" because at the end, all we can really do is guess what happened.

Ultimately, everyting is powered via electrons 🌞🙏

Watching this before sleep is so nice

Megalodon 108 one hundred and 8 meters….NO, NO, NO!!! That is a HUGE miscalculation. It is WRONG!!

Not a comet, but peppered by the trails of stuff comets leave behind when they swing close to the sun. We kinda drift through it. Apparently comets have the perfect invironment for the cornerstone molecules of life to form.

Megaladon was.NOT 108 meters.

Don't you mean even BETTER than dinosaurs?

"Most likely" != "possibly." You should clarify which one.

I really wonder when virion first decided to take residence in our little pool of slime?

Ever seen a fully grown forest let alone a tree?

I feel like we were an icy packed bunch of rocks, gravity held everything together then the ice melted and stayed within or gravity making oceans and gas helped create more water. I just cant see hot burned up comets dropping water crystals over time

Can I just point out that a lot of what is postulated in this video is highly circumstantial? I mean yes, these individually are observable phenomena. They do exist, but there are outliers and false positives throughout this theory of life. it cannot be presumed that life had a singular causal factor because of the chaos of factors involved. The bigger question is, what is life in the macrocosm? Is it the evolution of consciousness along side the laws of attraction, possibly? Could it be that it is everywhere and yet unseen because our notion of what life is is incomplete?

You skipped the introduction of water to the planet.

...i didn't know it looked terrible. Is this something considered to be common knowledge?

How does "some scientists believe" turn into "most likely an alien"? Some people believe the wotld is flat. Does that make it likely?

So you are telling me every organisms are my cousins

How do you know it looked terrible? You've got pictures?

Thinking does not create life maybe life creates thinking

Why are there so many religious people watching a video just to talk manure about what they don’t believe in anyway.

Funny how they talk about the formation of the Moon like that is a fact on how it happened while that idea is currently looking less likely.

Life is not alien to the planet it evolved on.

22:10 I caught one of these in the Ohio river about 20 years ago. I'll never forget it. It was about a foot long, and the entire body, including the teeth, looked like polished steel. I wish I could have taken a picture of it, but we didn't have phones that could just take pictures back then. I remember being so afraid of it, I cut the line instead of trying to open its mouth and fish out the hook with plyers like you normally would. The eyes looked just like they do in this fossil, except much shinier.

"The moon stablized and absolutely helped life be able to form." Almost sounds like it was planned. (obviously not by us, or the Us of today.)

@ 6:12, A blue whale with four pectoral fins? By that logic we should have four arms.

Great 1h+ video, this should become a series !

I like how Ark's dino model is in this video.

There are crocodiles bigger than that now Lolong was 20 ft 4 in and there are bodies of dead ones even bigger

If the planet was nce molten rock and at another time a frozen ice ball, how could life possibly have come froom here. ?

Looking at history of the earth all those who worry about global warming can be at peace knowing that sooner or later ice age will come back 😂

No, it's not that complex ? We are engineered I'd say?

The seeds of life came from the beginning of life from the gallery planets ect.

3:12 Africa existed 4 billion years ago?

Theres a probe drilling Uranus.

Saw two videos and decided to subscribe. Then the third one starts like that. Sheesh.

You forgot to say MAYBE

Primordial life coming to an Earth that has the Mediterranean in plane view?

Too many coincedences , We were helped to emerge and live on Earth

They found the biggest snake in my toilet

Excellent info. Thanks

If that's the case then there should be millions of planets just like earth and yet ...no life anywhere ..

What makes me laugh a little is the pictures / videos of earth being molten magma ball but there is clouds.... There was no clouds at that era. There was no water, no water vapor what so ever. At least could use material which at least looks real :D

Fallout series continues to be true with the big insect species, no wonder we thought that up, it happened lol

Blue Whale example obviously from Chernobyl. How many flippers? 😳

The study of the films that allow bubbles to form was the key to early cell membrane formation. Evolution trial and error leading all the way up to the Scrubbing Bubbles of today.

There's no need to bring up the past.

One septillion three hundred sextillion - Wow! I had no idea there was someone on YT who could express numbers instead of going for whales and giraffes or the "gross of scores of dozens" thing I need a calculator for to understand.

S time goes on organisms become more complex and more intelligent.

HOW DO THEY KNOW WHAT IS EARTH LOOK LIKE WHERE THERE ARE NO ONE LIVING THAT TIME

.. it's like Saruman created it with magic... and something else lazier took over

Of all the amazing things nature seems to pass along amd grow from organism to people. Why not conscious memories? Things just be , all new each time, to figure life out. It is like life is more concerned with creating life than living life itself

I'd just punch my way through the Jurassic era
