What is the name of the Buddhism 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.
