Whats your theory of first life formation on Earth?

It would be nice if you can write your own surmise, justification reasoning and observation from study or logic. your source doesn't matter as long as it is illustrable, demonstrable and/or logically reasoned. Kindly do not give reference to wikipedia or the bible or any other online source. Thanks
...And yes the when is also not necessary....if one can do that, it wuld be fantastic.
  • Don't have one
    We can know nothing, and my beliefs on the subject would have little bearing on my life, so, as an existentialist, I don't bother.

  • Spontaneous origin of organic materials
    All info is from (and cited in) the Ancestor’s Tale by Richard Dawkins, which I can’t find at the moment, but which I remember enough of to write a short summary. If I find it, I’ll add more in the comments.

    It has been demonstrated that (reproducing) life can spontaneously generate from an atmospheric mixture of the kind that would have existed when Earth was nothing but a hunk of rock covered in gasses and liquids. Free oxygen was unheard of, and the atmosphere was very acidic.

    Within the atmosphere, amino acids could, (And did…) combine in just the right way to create organic materiel. This was not life as we know it - it was even less than a whole cell. It was bits of what we call a cell, without a nucleus. All it could do was reproduce itself. That’s how life began, as modern science would indicate.
    Don’t get in a fix over the improbability of this. It really only had to happen once, but given the odds and the time frame, it probably actually happened several times. The time scale we’re talking to is so much longer than we can imagine.

    As a side note: It could never happen nowadays, because:
    1) the atmosphere is not right
    2) any living materiel would be absorbed or destroyed by the other living materiel that is far more evolved than it.

    The rest is evolution. TRUE evolution, not the "fish-landfish-mammel-ape-human" as depicted by the famous "evolution drawing."


    (I really reccomend the Ancestor's Tale to anyone who hasn't read it.
    And once you're done that, read the Blind Watchmaker, also by Dawkins. It pretty much debunks what he calls "Creationist Propaganda" and shows you how wonderful the world really is, and how it's even more awe-inspiring if you DON'T believe in a god.)

  • Seeding From a Meteor
    We have pretty good situation here for spontaneous production of amino acids, leading to proteins and prokaryotic cells.

    Another option would be space bacteria from a meteor impact, seeding the planet and evolving from there.

    A really cool symbiotic evolution is the cell that swallowed, but did not digest, the primitive mitochondria. The imperfection of this relationship is one of the proposed causes of aging.
