Buddhism does not accept a theory of God, or a creator. According to Buddhism, one's own actions are the creator, ultimately. Some people say that, from a certain angle, Buddhism is not a religion but rather a science of mind.
Here's an example: someone says, "Master, please hand me the knife," and he hands them the knife, blade first. "Please give me the other end," he says. And the master replies, "What would you do with the other end?" This is answering an everyday matter in terms of the metaphysical. When the question is, "Master, what is the fundamental principle of Buddhism?" Then he replies, "There is enough breeze in this fan to keep me cool." That is answering the metaphysical in terms of the everyday, and that is, more or less, the principle zen works on. The mundane and the sacred are one and the same.
I think oysters are more beautiful than any religion,' he resumed presently. 'They not only forgive our unkindness to them; they justify it, they incite us to go on being perfectly horrid to them. Once they arrive at the supper-table they seem to enter thoroughly into the spirit of the thing. There's nothing in Christianity or Buddhism that quite matches the sympathetic unselfishness of an oyster.
If science proves facts that conflict with Buddhist understanding, Buddhism must change accordingly. We should always adopt a view that accords with the facts.
