I think there is a LOT we don’t know.
I do not believe we suddenly became self-aware 10,000 years ago- I would find it easy to believe we’ve been around for hundreds of thousands - if not millions - of years before, AND that there has been one or more, global catastrophe’s that nearly wiped out humanity.
The Flood, for example.
That pyramids and sphinx are way older than we are led to believe. It would be awesome if they actually contained secret caverns of knowledge that people saved for us.
