Again, all of your givens assume that they would actually be from another part of the universe, while a demon/alien would be inter-deminionsal. In other words, they are already here.

Of course I would assume that aliens would be from this universe. That's all there is. I see no reason to believe that they would come from Hell, Valhalla, Middle Earth, or any other mythical dimension. As for them already being here, let's see the evidence.

There's little sense in debating the issue of demons/aliens further since you are still hung up on the "god" thing. That's another topic on another thread for another time.

Um, you brought up God, not me.

Of course I would assume that aliens would be from this universe. That's all there is. I see no reason to believe that they would come from Hell, Valhalla, Middle Earth, or any other mythical dimension.

But you also just laid out a great case of why there' little chance of creatures from elsewhere in this universe finding us and getting here. You have me convinced that it's practically impossible; therefore, if some exotic beings show up with technology beyond our wildest dreams and claiming to be from elsewhere in the universe, I'll know they are lying and can't possibly be from elsewhere in the universe. That will certainly play into my reasons for believing that they are demonic, so we're right back to where we started.
