EDIT: Part of the reason that people of thousands of years ago - or even hundreds - didn't become as advanced as we, technologically, is that the changing physics of the universe made it very difficult for them determine from one year to the next how to use the sciences.
Did your priest tell you this? Certainly doesn't say it in the bible, so where are you getting this nonsense?
The physics of the universe does not change. You are a brainwashed fool.
