Funny but in a sense one must have a rather complete knowledge of universes to know the answer. Perhaps it will turn out that it is impossible to have a universe without a God.OK so we all agree that the possibility exists that the Qur'an is not perfect.
Good.
Second question: Does the possibility exist that there is no God?
Possibility generally means - given what we know can this or that happen.
But it also is used to mean - can this or that happen, period.
I think your question is often answered as if we know the answer to the second question, which we don't.
