I'm glad you've experienced that epiphany, Spaw. You are clearly on a path out of the darkness and into the light of wisdom and understanding. ;-)

Jack - Yeah, the Greys are interesting. If they are indeed real beings, then I think they might have quite a different form of reproduction to ours. They might lay eggs, for instance, as reptiles do. Or they might bud, somewhat as plants do.

I think your reasoning on the likelihood of a humanoid form developing is spot on. If you want to use tools and create things with them, a humanoid type of form is extremely handy.
