Bernie Wides, The Naturalist, 2001: A Space Odyssey, the Earth is 4.6 billion years old, the solar system formed from the same body of material, life started approximately a billion years after the formation of Earth, conditions used to be very different, there was no breathable oxygen, black smokers, deep sea volcanoes, thermal vents, we don't need direct sunshine, lightning storms, carbon based proteins and enzymes, we need water carbon hydrogen oxygen and nitrogen for life on earth, those are very common elements, out gassing of the cooling earth produced hydrogen and oxygen, the impact of hundreds of thousands of comets, early cooling periods of the earth, comets are frozen water and dust, they create bodies of water, some people believe that life traveled from another origin, viruses, panspermia, transpermia, Gaia hypothesis,Life On Earth (7:34)

early life on Earth was very simple, when the Earth was 2 billion years old the atmosphere changed drastically, methane, carbon dioxide, little one celled organisms gave off oxygen during photosynthesis, carbon dioxide changed and free oxygen was released, life became more complex, some lifeforms got wiped out by cosmic impacts, life seems to want to be on Earth, evolution, there is not a straight line from bacteria to humans, dinosaurs, Galapagos, Mars, liquid water, Europa, Jupiter, Cambrian explosion, Darwin finches, astronomer, The Museum Of Natural History,Planets & The Night Sky (9:21)
