EARLY LIFE - (c 3 Billion BC)
Without light, there would be no life. Life was dependent on three things being present: a.) the basic long molecule building block, carbon, b.) water, and c.) light. The Earth had all three. Eventually the oceans formed a rich organic soup that ultimately bore life. The oldest verified evidence of life comes from Rhodesia, where rocks formed approximately 3 billion years ago, bear 'stromatolites', the fossilized remains of algae.
Originally our atmosphere contained; hydrogen, helium, nitrogen, methane, ammonia and water vapor. For millions of years, the waste product of oxygen, from the ocean's algae, bubbled up out of the sea and into the atmosphere. Gaseous oxygen reacted strongly with the methane and ammonia in the atmosphere, turning it into carbon dioxide and water vapor. Over time, methane, ammonia and carbon dioxide were almost eliminated from the atmosphere. As oxygen began to build up in the atmosphere, the usual oxygen module (0-2) began to absorb ultraviolet wavelengths from
