"Believe nothing, no matter where you read it or who has said it, not even if I have said it, unless it agrees with your own reason and your own common sense."~ The Buddha
It is interesting that the Buddha says not to believe him if there is no legitimate reason. But reason and common sense usually don't have much room in religions. If the Buddha doesn't want to be believed as a God, the Buddhism is a religion without God.
Then, can a religion without God be a religion? In fact, there are many Buddhas in Buddhism. Buddhas are not treated by believers as Gods but are considered as the enlightened beings. The good news is, everyone has the opportunity to become enlightened, - to become a Buddha.
Another question is, what is the true belief and what should you believe? According to the Buddha's teaching, the ultimate belief is self-belief. If you don't believe yourself, you can't really believe any God of your choice. All Buddha's teaching is focused on benevolence. There is no absolute truth but absolute love. Buddhism is not about believe, it is about love.
