"It seems to me that by saying maybe we were created by “aliens,” you are conceding the existence of a supernatural entity-—a god or gods."

How do you get from "aliens designed humans" to the "existence of a supernatural entity"? I don't follow. There need be nothing supernatural about the aliens. It's entirely plausible that they possess a super intelligence and advanced technology, and that they were able to engineer our DNA and create life. None of this crosses over into the supernatural.

As to your morality argument, I think that's another issue. We can go there if you'd like, but I don't believe it's directly related to the original topic.

How do you get from “aliens designed humans” to the “existence of a supernatural entity”?

Easy! The creator is always superior to the creation, by definition. “Supernatural,” as I pointed out, only means that the entity is above (”super”)—that is, excepted from or not bound by-—nature (the “natural” forces that bind us, the created).

Obviously, who/whatever created us is not bound by the same natural forces that bind us, because we haven’t been able to create at the same level.

So, if aliens created humans, by definition those aliens had to have power beyond what we have and had to be above (not bound by) the natural forces that bind us, the created.

So, if in fact aliens created humans, those aliens would have to be supernatural entities compared to us and our nature.

By definition, they would have to have more power than that possessed by what they created.
