All the books would tell it that way, and in a thousand years’ time it will be the truth, just as what was once the bottom of the sea is now a mountaintop. Ask the wise men at the university what truth is and they’ll tell you it’s the consensus of informed and qualified scholars, based on the best evidence available. Availability is governed by what gets burned in the meanwhile, but I see no real problem with that. All living things change or else they die, and why should the truth be any different?
