Exactly, no one can, because your premise is wrong.

That was pre-science. If you can't find a modern day example there's a reason for that, the wheel of science only turns one way, forward. New science rarely if ever disproves past science, what it does is give us more accurate theories; the old theories are still correct within the framework they were made in. Einstein for example, didn't prove Newton wrong, he just had a theory that was even more accurate than Newton's.
It's not ego, it's how the process is meant to work.
