Aliens created humans. The humans didn’t like being created by other intelligent life, they wanted to be the only intelligent life. So the Aliens made Gods for the people, to keep them from killing each other.
Once you know everything, you can create divine beings.
Religious nut jobs will think this is bat shit crazy, because they don’t like the truth, Aliens exist, get over it.
You wouldn’t exist if Aliens didn’t.
Who created the Aliens? The same question would apply if Aliens didn’t make Gods, who created God? Existence doesn’t make sense.
