The "Almighty" thing is usually from monotheistic religions (Judaism, Christianism, Islam...) but polytheistic religions that have multiple deities usually include a heirarchy where a more abstract kind of Creator (which can be "Nature/the Absolute/Chosmos/Chaos/the Soul of the Universe/whatever") gives origin to the "less abstract" deities who in turn become notoriously more and more "human-like"... Then you ALSO have Asian religions like Shinto and Taoism, where IIRC there aren't just those who're "born as gods", but any creature who became a god by "evolving": in Shinto and fictionalized Tao-based Chinese stories any creature can become a "god" by working their way up through pain and effort and "evolving" step by step, all the way, from ordinary, to "god / god-like" level...and they get called "gods" but they're more like "spiritually evolved" or "enlightened beings" who often become "administrators of The Creation" but are subordinated to "Nature/the Absolute/the Soul of the Universe/whatever"...
Its funny.. If there is someone who created the god of creation that means they are not all powerful.. If god is bound by rules then they are not gods.
