sm29: I have to second yid.period’s comment. There are many historical, sociological, and anthropological explanations for the Jewish people’s survival over the course of three millenia. Our survival is not a “proof,” it is merely an example of God’s guiding hand for those that already believe that hand is really there.
Also, there is not a single science-based “proof” that I have heard that cannot be explained away by someone that knows enough of the scientific literature. The problem with bringing “proofs” based on “secular” knowledge is the (1) that knowledge is always changing, so what is a “proof” today will be discredited tomorrow, and (2) the academic community is so large and diverse that for every conclusion and theory you find to support or “prove” God’s existence, you will find many other approaches that undermine that “proof” and tend to disprove God’s existence.
Thats why these kinds of proofs typically do not satisfy curious, critical, well-educated, academic minds.
