A myth made up of numerous stories of the old ages.

I remember reading an anecdote about a young man who said he didn't believe in a supreme being, and the way a priest / pastor / whatever replied, "Please describe for me the God you don't believe in." The poor kid mumbled something about a wild eyed, vengeful lunatic with a rather useless beard, and the priest said, "I don't believe in that either."

All the while, I kept thinking, "What a magnificently stupid question," and "Is that supposed to be proof that there is a supreme being after all?" All these years later, I find myself saying, "It sure is" and "It definitely isn't," which settles any residual dust the memory might have kicked up.

A philosophical product of the human Ego. The SuperEgo is the awareness of sel-awareness. All else is just narcissism.

God is the outward expression of an inner character weakness.

Why don't you explain your god? As for me, I am confident that no god exists.

For me... God is a mythological character that is a personification of the collective forces of the universe, and is an emergent property of the human mind designed by evolution.

I would have to say that any sentient being that was so powerful that it could create the universe out of itself would have to have a consciousness so far removed from humankind that it would be incomprehensible to humanity, less of a connection than that between single celled organisms and humans. The gods described in the various holy books are more of an anthropomorphic deity that humans can relate to, at times loving and nurturing, at other times jealous and vengeful but most of the time just plain homicidal.
As an atheist I can accept the concept of a universal life force, indifferent to my personal needs and wants or even a god particle like Higgs boson with roots to the Big Bang theory but a sentient being that sprang out of itself and then created everything else is not acceptable to me anymore than an angry, old man in the sky deity is acceptable as anything more than a Bronze Age fairy tale. That said however, if an angry old man came down from the sky and clearly demonstrated god powers then I would readily change my mind but I wouldn't be blindly believing in something, rather I would be accepting a change in my perceived reality.

God - the natural forces that drive the Universe

Your definition is not a bad definition to be agnostic/atheist about. Creation ex Nihilo, however, is a relatively modern concept. By relatively modern, I mean the early Roman Catholic Church (Latin). Creation ex Nihilo essentially originated as a way of saying to the pagans, "Our God is greater than yours. He can create out of nothing." Note also that Creation ex Nihilo is not explicitly found in Genesis. The ancients thought that creation out of nothing was completely illogical. Nothing comes from nothing (ex nihilo nihil fit). (Yes, Shakespeare played on this saying in King Lear.) Consequently, the ancient Greeks believed that there was always some sort of matter or primordial stuff which a creator God organized into creation as we see it (Creation ex Materia).

no place for any god (omnipotent being) in my multiverse, where Nature, an omnipotent force, rules.

I can't describe a god of my choice... i don't want one.

Define a nuh. Nuhs are mythical creatures that live in Nuhia which also does not exist. So you tell me what you think they look like?
