[I see my hands]

Imo, Fermi has the last word on this matter.

Have you ever read about Edgar Cayce? In his trances he talked about reincarnation, even though (I think) he was a Christian. Anyway - he thought there were a finite # of souls - and that while there may be life in many forms out there in the universe - they were nothing without the souls. He said that the souls sort of migrate as a group, experiencing different kinds of lives as they go. I would always think of bugs when I read this - how they might swarm onto an apple tree for a while, use it up, then move on to something else. Requires a whole 'nother belief in something we have no proof of - souls - but could explain the lack of proof of ET's - only one place at a time is occupied by the life that has souls. Probably couldn't be further from the mind of Fermi - but interesting.
