And what would it have hurt to explore and learn from this practice? Squashed just for religious political reasons. I am sure a LOT of this has happened throughout history. Just look at the destruction of the Library at Alexandria. That destruction was based on faith. And it is not selective, every faith has done this throughout history. And they still manipulate and control knowledge when they can get away with it, especially if they are funding it. But when anything is trying to be proven as extremely “newer”, I immediately have suspicions about the source and desired outcome.
Other “newer” stuff is rejected for the simple reason that some important “researcher” has made their reputation on something else that the new stuff might challenge. It often has nothing to do with religion. Then there is the fear of change that also impedes progress.
