The only higher beings are aliens from other planets that are more intelligent than us.
Perhaps they have visited earth at various points throughout the existence of man and enabled/progressed us in various ways, and these things have been attributed to god.
Sumerian and Babylonian Hieroglyphics are full of bizarre symbols of things that looked like Aliens and spaceships from above. Especially with certain amazing old civilization wonders built that would be impossible in those days with the technology at hand.
So your statement is a strong possibility.
