Many Buddhists do not believe in God. Some do.
Buddhism is atheist friendly
My understanding is that Buddhism is not a belief system, you don't have to believe in gods (or anything else).
Just to accept as a working hypothesis that you can develop the skills to end suffering, which is not hard to do once you see the benefits of meditation.
This is Unlike theistic religions where you will be sent to hell if you don't believe in god and his prophet(s).
