I like that idea too; that we aren't suited for either at this point. I was trying to answer Darwin's question of where are all of the fossil records of us becoming the modern homo sapien sapien or whatever we are called now; maybe all of those fossils are inside the planet, fossils that would possibly even show the perfect curve of evolution which allowed us to advance cerebrally, how we got so smart compared to the surface critters before we got out here. I'm still looking for that missing link I guess. Next time... maybe we're from Mars! No seriously I think I'll back off of this topic for a while now.
