If one believes that religion is a figment of man's imagination then all are wrong because there would then be no God.

But if Deity exists, then reality is not determined by what the various religions believe is right or wrong anymore than the beliefs of two second graders one of whom fervently believes that 2 plus 2 equals 3 and the other of whom is just as emphatic in his belief that 2 plus 2 equals 5.

Reality is not determined by what humans believe is true. As a scientist, you should realize this.

If Deity exists then reality is determined by Deity and not by the beliefs of humans.

If Deity does not exist then reality is also not determined by what humans believe.
