" So you're a Raelian.
Cool."
Nope.
Just putting forth a 'theory' that the current intelligent civilization may have not been the first.
Besides. Try as I may, I just can't seem to get my tinfoil hat to stay on straight!
No, you're putting forth a hypothesis, not a theory. And that's the problem with "ID" -- it doesn't rise to the level of an actual scientific theory, and should not be (mis)represented (especially in schools) as if it did.
You're not the first (and that's a hypothesis - not a theory, at least until there's some supporting evidence).
Giordano Bruno was probably the earliest to speculate on this.
Funny how "competing theories" were resolved in the Church.
