Belief in one God is all that is required to be a mason, one doesn't necessarily have to believe the accounts in the bible, I feel the bible is there because its a spiritual and moral book and one can reflect on the allegorical teachings in it, which is why any monotheistic spiritual book can be present. If you believe I'm the accounts of the bible, that's fine, it's not my place to tell you what to believe, but scientist labor very hard to prove these facts and we shouldn't just look away because our faith may say otherwise. I believe the GAOTU is a all pervading consciousness, the universe and nature are God.
