Well, again I will leave most errors for others to correct, but I simply could not pass this by.
That is why many models state that earths early atmosphere had much less oxygen in it, but there is no other evidence to suggest what amount of oxygen was in the air 4 billion years ago. photosynthesis is a very common chemical reaction now but how common was it 4 billion years ago.
Wow.
As you may or may not be aware, photosynthesis is a process used by plants and some other organisms to convert energy from the sun to food. Think about that for a moment.
Your problem is that we don't know how much photosynthesis was going on 4 billion years ago and, thus, we don't know what the conditions on Earth were before life began.
Think about that just a bit more. If you don't see the glaring problem here, I'm quite certain you're not ready to talk to anyone about anything remotely related to science.
