I don't really care to be honest. If you want to run around thinking there were never any slaves throughout history and people just built the pyramids because they felt like it be my guest.
I do find it surprising that with the weight of all the 'experts opinions' comes zero evidence worth talking about.
I have asked you for evidence repeatedly but to no avail. I am not running around hunting the internet trying to 'prove' that slavery existed throughout history.
The leap you make from 'evidence suggests they didn't use slaves to build the pyramids' to "there were never any slaves throughout history" is an astounding one.
Its hard to really interact with that sort of nonsensical approach.
There is evidence. Evidence the the world's experts find worth talking about.
