The teachings of Buddha never denies gods existence, but it says once has to achieve salvation through rigourous punishments to the body. He also said that good karma leads you into the light of nirvana whereas bad karma shows you to the world of yama. And what did you say about Buddha telling no use in praying to god? Then why does he sit in the holy lotus posture and meditate? Now you are hurting Buddhists by saying that they are praying to Buddha in their temples without any use, be careful. This is offensive.
