[extropy-chat] Deep-earth methane generation

[Bret Kulakovich]

There is also the case that most of our current atmosphere was 
metabolized by cyano algae and bacteria, even earlier than the 
dinosaurs.

Could the volume of that early flora/fauna have been compressed/buried 
and represented today? Perhaps there is a rough number. My 
understanding is that it would be a large number at that.
