The photo looks like it's of their Head of Athena which was found in Israel despite being made from Greek marble and representing a Greek goddess. It is hard evidence that non-judeo-christian belief systems existed and interacted, and were at least somewhat allowed to do so, before the Talmud but still inside Jewish territory. Specifically, groups like the Cult of Zeus-Akrios, which some people say influenced the development of Judaism and the writing of the Talmud around the time Judaism and Christianity split.

When your worldview requires that you follow the Talmud and that it is the foundations of Judaism and divine law handed down through Moses and oral rabbinic tradition only, but you have evidence that predates the Talmud which demonstrates visible and open polytheistic religious integration in a society you believe was only monotheist judeo-christian... it gets really difficult to dismiss some uncanny similarities between the religions. Similarities that are otherwise easily explained by religions stealing things from other older religions they encountered.

The very idea his God was created partly from pieces of a polytheistic religion is against everything he was raised to believe as truth. His brain probably broke trying to process it.
