In that sense, I have found "The Dawn of Everything", by David Graeber fantastically good at debunking so many previous preconceptions and clarifying with cross-checking historical records some things we were taught that are arguably wrong and biased towards the western-european culture.

I correct myself, I have found all books by him just as good in that respect.

So, new eyes are great, new perspectives are awesome. If Graham Hancock were just a bit as through with his fact checking as David Graeber was, it would have been even better.
