Hehe, well I was actually more concerned with the implication by the letter writer that his religion is right when he says the Egyptians were wrong in their religious beliefs. In a thousand years I suspect religion will be a lot different to the way it is today.
But you’re right. In a thousand years there might be more evidence of ancient religions than present day religions and cultures because of our digital legacy! We’re still at the early stages of moving information into a digital medium and the tools to manage them are improving. Long term storage is still a problem though.
