Technically Buddhism is not a religion and it has no god.

Buddha never bothered about God. In fact Buddhism is an atheistic religion like Jainism. Later the followers of Buddha made him a God. Only after Mahayana Buddhism came he was made God. In Hinayana Buddhism Buddha was not a God.

There is reference, though, in Buddhist text, to the "First Cause." Since God is the Creator of the universe and all that is therein, then God is the First Cause.

There is no offical god in Buddhism.

Buddha is the god of Buddhism.
