I agree I probably didn't answer the question directly either. Not meant to 'pigeon hole you', I should have made it more clear from my statements that I'm open-minded to the possibilities of advanced ETs on earth, but doubtful. I think it's plausible.
On a personal level, I wish there were (but that's another philosophical discussion altogether). On an objective evalation of the available facts, I find nothing compelling enough to convince me there are. Also, from working in the areas discussed, I've seen nothing ET-like that wasn't contrived by human imagination.
