I don't think at the time there was distinction between religion, astrology, science, medicine and healthcare.
The priests had the knowledge, while the commoners were mostly illiterate.
During the Predynastic Period pigs were considered unclean in Upper Egypt but were domesticated and eaten in Lower Egypt. During the Dynastic Period Pigs were thought to be unclean in some areas and among the wealthier classes. Herodotus states that people who raised and ate pig were shunned but archaeological evidence suggests that although technically unclean, pork was still popular with many poorer Egyptians.
Moses or not, the word "Israel" was found in Egyptian scripts. "Hapiru" king "Yakubu" also mentioned in Egyptian sources - cognates with Hebrew Yaakov.
There are enough evidence, that ancient Egyptians and ancient Israelis had a contact.
I took a biblical archaeology class as an undergrad and both our teacher and every text we read were very cautious about making this link. There simply isn't very much evidence for who the 'PRW (apiru or whatever) were; we don't even know if it's a particular tribe/identity or just a catch-all for brigands and outlaws. Similarly, we don't have any historical evidence for what Israelite society was like before ~1000BC and definitely nothing about 2000BC (when the word apiru starts appearing).
I agree that the ancient documents about marauding apiru might be referring to Hebrews, but we really should keep our Bayesian hats on when evaluating archaeological evidence.
As for "Yakubu" and "Israel", any citations? Are those in one of the Amarna letters?
