That’s conservatism! ;-)
If it ain't broke...
Just to make my own fun and poke the bear a little -- it seems odd that no one has ever saddled on the more or less fixed paleolithic tool set to 'prove' that the centuries-long lives of Old Testament figures were correct, and that they were all Neandertals, making the tools they'd made for hundreds or even thousands of years. :^)
