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.
Now, really! Take a closer look at my two alternatives:

we have two alternatives for explaining our spatially separated co-existence: either abiogenesis occurs multi-regionally or panspermia really works.
Either abiogernesis is multi-regional or it isn't. If it is then it could have happened on both planets. If it isn't, then the Johnny Appleseed of panspermia had to carry those precious spores from the planet that hosted abiogenesis to the one that didn't. No?
