How Did Life Begin On Earth? | Science Greatest Mysteries | BBC Earth Science 

Very cute

nerd

Little has been done since the Miller/Urey experiments in the 50's. All of those amino acids were racemic meaning they were left and right handed structurally. You have to have non racemix acids(one handed). We do not have a good explanation for how early earth dealt with that.

Yes, and Conway's game of life provides proof of concept as well.

The problem is that the experiment destroyed more than it created. How can this demonstrate that naturalistic processes may cause life, if the evidence from the experiment itself is actually refuting it?

Would be great to have him on for an interview

Were you in the first world war? No? Then it did not happen.

😂😂😂😂let them come n visit it to save their energy of returning mars

It's most likely useless for this experiment due to billions of years of soil changes & plant growth.

_Recalls_ Stanley _Miller's_ experiment, not 'remembers Stanley Miller experiment'.

@@mcarp555 thanks for grammatical correction

"What the heeell you say?

Well said , Limits are limits no one allows to cross then why would Almighty Creator allow. The most powerful fact regarding this is the most vigilant powerful human brains have been working through unknown period of history to find answer of this simple set of questions , respect your logical suggestion.

Hear hear! 👏 I dream of the day mankind rids itself of religion and all the damage it does!

'You will have knowledge of good and evil.' There hasn't been peace, since then.

The most accepted theory of the formation of life is connected to black smoker hydrothermal vents on deep seafloor, which is way below the photic zone. The video presents a very specific (and wild) theory. The first forms of life are widely thought to be chemoautrotrophic, meaning that they didn't need sunlight to thrive.

Who created the Sun and universe.... ???

@@tatigomez3046 Thermonuclear processes and gravity created the Sun, and the Big Bang is a really tricky quantum physics story.

@Gabor-df1ov my theory on the universe is as follows: Space time and matter are all infinite which means that they've been in existence forever and if you also add infinite cycles into the equation then there's no need for a creator because infinite means no beginning and no end. In the infinite universe anything that can happen will happen an infinite amount of times. Y'all have a nice Infinite day now. ♾️👍

No,bacteria are alive, so it doesn't answer where life comes from. More general, the hypothesis is that multicellular life evolved from single celled life, for which we have no actual evidence.

@@SojournerDidimus Have you heard of evolution? Humans share roughly 145 genes with bacteria and virus. That alone shows we evolved from single-celled bacteria. If you will keep peddling misinformation and arguing disingenuously as creationist by reporting my comment, I will be here.

Single cell organisms are complex, but not as complex as multicellular organisms like humans, plants and animals. The organelles of single cell organisms are fewer unlike in multicellular life. The organelles of single-celled organisms perform more basic individual functions and interacts with other parts to perform other functions that creates synergy to the overall biochemical reaction within the cell. But this is on more limited basis-- like eating, metabolism, responding to stimuli and excretion. More complex multicellular life forms, on the other hand, can perform more. The behaviour and metabolism of single-celled and multicellular organisms are incomparable. Scientists could easily observe almost all the behaviour and metabolism of single-celled organisms and run out of what are to be observed when studied long enough. Because they're simple life. Whereas, multicellular organisms have more complex matabolism and behaviour, which is harder to understand. That's why we have the science of toxicology, pharmacodynamics and pharmacokinetics on humans and animals to understand how (bio)chemicals interact with the body. I should mention that the number of base pairs in DNA and amino acid function of single-celled organisms are easily sequenced, or identified and catalogued. It took weeks, months or just a couple year formost bacterial cells to be sequenced in the early days of DNA fingerprinting; but 13 years for the entire human genome to be sequenced. Many more genome projects are still undegoing as we speak And many of these findings found that much of the DNA in almost all organisms do not serve any function for the organism to live. If that is by design, then it's a very inefficient and wasteful one.

​@@impalabeeperDoes you think it's extremely pretentious to sequence the genome and state that there is junk DNA simply because we haven't found its function yet?

@@SojournerDidimus Some of the junk sequences have shown to have functions. But with respect to the creationist argument that everything is by design, these junk DNA are waste and pointless to begin with if a supposed creator put them there in the first place.

@@impalabeeper Can you explain that again, but without using the word junk?

@@SojournerDidimus Majority of DNA sequences in all organisms turned out not to have any functions and thus you can live without them. Hence, the term "junk DNA". If a designer puts them there for purpose, then what exactly is the purpose of putting them? It's a waste of energy to replicate DNA with all these useless, non-functional sequences. That does not sound intelligent, purposeful design to life if there is a supposed creator, would you not agree?

Panspermia is not much different from God creation argument. It doesnt answer the fundamental question, how did life came to be in the first place

No. The heat of entering Earth's atmosphere is high enough to melt gold, which is more than enough to disintegrate most biomolecules.

Fair point man. Unless by some chance there were amino acids locked into the rock internally that may survive atmos entry. But who knows.. I can only make a stab of a guess. I wonder if we will ever find out for sure.@@dweebteambuilderjones7627

Has been done already. We just missed the most exciting moment though, so now we are trying to repeat it.

Did you watch, and understand anything in the video?

That's why the return to Mars is necessary. Those impact craters still exist and may have traces of the sodium cyanide, and amino acids

We performed it millions of times with an invisible sky creep and nothing happened.

@@JaneJetsin Discovering how life began would make the "Invisible sky creep" obsolete.Grow a neuron.

That's just moving the goalpost; if from somewhere else, how did it get there? Eventually you will need an uncaused cause, that's where God created life, and heaven, and earth.

LOL Yeah Adam from mud & Eve from a rib & they had no daughter. Totally makes sense 😂

and god is 3rd gender😆😆😆

The fool is a person who is gullible enough to just believe the words written in any old book to be true.

Do you really expect to change hearts and minds by doing a bare minimum post online? It’s arguable you’re doing the “devil’s work” by being annoyingly naive.

That’s because there is no god, it’s only a story made up by humans to explain something they couldn’t understand. Science today helps us to understand what is happening and has happened!

Wat

On the contrary, we should widen our view and consider there is more than one supposed cause. Of course only one is actually true, but we might just miss it be exploring only one of them.

Lol

Actually Luke, earth created God. We are a product of some beautiful and chaotic chemistry that occurred on a very different earth billions of years ago. The universe created the earth, the earth created life, which gave rise to humans, who devised and conjured up our ideas of gods. This was to serve many needs of our long begotten ancestors providing some solace in believing that death was not the end of life, that we are special and created above other life. God offered comfort to the sick and vulnerable, enabled powerful people to better control their subjects and helped bring people together with common ground (it also did the opposite when conflicting views clashed and many died for these foolish beliefs. We created God. We are God. This is the only life you have. If you want to know what death is like, it's actually quite simple: it's like all the time and moments that occurred before you were ever born. You don't exist before your birth and that's essentially all death will be - not existing. We shouldn't believe something just because it feels good to do so.

Yea and some guy splits oceans. Really believe the lies?

What a pathetic, intellectually lazy comment. You have no evidence that anything was created, yet you make irrational assertions and baseless claims while we, the scientists, are out there actually doing the work to find the answer.
