Wrong. Angels are not corporeal beings. How the hell would they procreate without sexual organs or semen? The can merely "appear" as humans through the manipulation of light (as St. Thomas Aquinas explains).
I have to conclude that this was a test of some sort, most likely site/server test. I don't think Q, if he legitimately has the highest level security clearance, would answer a question of this magnitude without better detail. In fact, I don't think it responsible to answer that at all in this type of forum.
I also now think that a good majority of people in here would believe whatever the hell Q said, no matter how ridiculous. Vampires and werewolves next?
