1.
(in Christianity and other monotheistic religions) the creator and ruler of the universe and source of all moral authority; the supreme being.

2.
(in certain other religions) a superhuman being or spirit worshipped as having power over nature or human fortunes; a deity.

Can anyone be more specific?

Does this 'supreme being/superhuman being' have a human form?

Is it an old man sitting on a cloud?

I'm curious.
