Einstein was not a particularly religious man, though he was sort of a believer. he was essentially a Reformed Jew. Have you ever seen a photo of Einstien in a yamulke? I haven't. Orthodox Jewish men never leave the house without one.
It does not bother me that some scientists are believers. If people, get religion drummed into them when they are very young, they will be believers, as the religion gets to them before they are capable of logical thought.
I think that a lot of scientists are actually atheists and agnostics and allow others to think they are believers because in many parts of American society you are expected to be a believer. I worked for a church-related college for 32 years, but I never discussed religion with students or any faculty members that were not my close friends. There is no point to it. There are no rewards for being an evangelical agnostic or atheist.
Some scientists, like Neil DeGrasse Tyson, for whom I have great respect, tells people that he does not believe anything without proof and that he sees no proof that any God exists.
A lot of people have the mistaken view that if you question the Bible as accurate, then you do not believe in anything. They see only two options: either you swallow the whole tale Holy Trinity myths and all, or you "don't believe in anything." But of course this is not true. God could have been a long absent Creator. Then universe could be eternal. It is in fact eternal for all practical purposes for humans.
I observe that believers feel obliged to post "Jesus is coming soon" and "Jesus viene ya" all over the place. No one feels obliged to tell you that Money exists, or that time exists or that weather exists. This is because we don't need signs, the evidence is apparent.
