The Buddha is no almighty, immortal deity that reigns and watches over humans. The Buddha was a human being who had a deep insight into the nature of our discomfort and the nature of the universe.
Buddhism is a path that helps us recognize our own suffering and a way out of the suffering.
Buddhism does not require an especially esoteric mind or believe in miracles. A very important aspect of the practice is direct experience and instead of having to blindly accept a dogmatic message you are encouraged to experience and investigate much like the scientific method.
