Hi, I'm a physicist with a layman's interest in biology. I was just wondering what the physical requirements for the origin of life on Earth are expected to be. So, for example, pressure range, temperature range, chemicals needed etc. If this has an answer, how confident is the community, or are there many competing hypotheses? You can tell me if it's valid or not, but the discussion may be limited to life which began on, i.e. not from a meteor or whatever. *Idk if this would be more appropriate in the biology, chemistry or physics section* so, i guess it can be moved to either (if that's how it works). Cheers, InsertName.
