The Christian Bible is not historically reliable and cannot be cited as evidence.
I am posting in this thread to provide as much factual information as I can to the question asked. We can’t really know much about Jesus, but we can know something about the cultural context he supposedly grew up in, and he grew up in a context where there is virtually no chance he could have had access to formal education.
Oral facility with Hebrew scripture? Quite possibly. I would even say probably. Actual book learning - nope.
