Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

I see the Litvak seminaries for girls in Bnei Brak do not want give graduation diplomas to girls that are after that off to get a secular education. This makes sense to me since the girls would be going into ''education'' which means ''critical race theory''. The humanities and social studies departments of universities ought to be closed. [Allan bloom pointed in 1990 the crisis but now there is no crisis. these two parts of the modern university are poison.]
