Nih\u010de ne ve, kako se je \u017eivljenje na Zemlji za\u010delo. Ve\u010dina znanstvenikov meni, da se je za\u010delo v teko\u010di vodi.

Mnogi med njimi so verjetno pri\u0161li na Zemljo z padajo\u010dimi meteoriti in kometi. Na nek na\u010din so se te preproste \u2018organske\u2019 kemikalije zdru\u017eile in oblikovale bolj zapletene molekule.
