Well, I agree with Faldage....life has evolved this way, and if it hadn't, it would have evolved 'that way' or some (other) way, and surely it has in places we haven't yet found or perhaps even conceived of (and may not ever as human beings; we are constrained by the very fact of our existence). And I find that fascinating.

"What it boils down to, as far as I'm concerned, is that the universe is neither compelled nor constrained by our imagination or lack of imagination". -faldage

But *we* apparently are. And that's why I try to let set my imagination free....I let it roam around with ideas like qanats and speleogenesis, high altitude sprites and collective minds...somehow its all part of the larger evolving....imho, anyway....
