> Yes, I know I'm treading on some dearly-held religious beliefs .... > what exists or doesn't exist in the universe that's not visible is pure unscientific speculation I don't see anyone saying that the existence of aliens aren't speculation or that "aliens exists" (or your: "aliens don't exist") isn't just a personal belief as stupid to argue about as religion. But as countless wars have shown, people (like you) will try to create conflict from differing personal beliefs. Just because you drop "Occam's razor" doesn't make your belief the correct one.
