This moon ain't big enough for the two of us...
Koar, OSS! I find the idea of COMOLD interesting. While I can see where Zendexor is coming from, it doesn't bother me like it does him. (Although the fossil record ties us pretty closely to Earth.)
I wonder what people think of the idea of panspermia to explain the similarities of life throughout the solar system. I think it avoids the disappointment expressed in COMOLD while still providing some semblance of an explanation for why men-like beings may exist on multiple worlds.
