LOL!Yes we have knowledge and reasoning that those ancient sheep kissers could have only dreamt of. You are living in a fantasy world not reality.
If Jesus had existed Joseph would have likely been thighing him, Jesus would have wiped his @ss with his bare hand and they didn't exactly have anti microbial soaps back then. The world at that time was dark and disease filled. You were lucky to reach adulthood.
No, they had knowledge of science that only WE could dream of. There are still countless mysterious that cannot yet be explained. You are the one living in a fantasy world if it is your opinion that we have a monopoly of all knowledge throughout all history.
And yes, they did have anti-microbial soaps. First, anti-microbial is a scam. Soap has been around 3000 years, and was strong enough to remove hair when made with too much lye. Your ignorance of even the basic technological knowledge of the ancient worlds testifies to you ignorance ... and arrogance.
Dark and diseased filled indeed. We have more diseases and darkness today, then ever the ancients could imagine. We would be total barbarians compared to them, by any standard.
