we have two alternatives for explaining our spatially separated co-existence: either abiogenesis occurs multi-regionally or panspermia really works
um, hoot, you do realize that panspermia requires abiogenesis, right? It might explain how life got to a planet, but not how life got started. i mean jeez, you have a whole thread (at 305 posts) to figure that out. you still haven't apparently.
and if you want to continue that whole bit about DNA and digital codes, there's a new thread for that.
