But that's the point! New information such as these discoveries in the Amazon show that the stories told by "mainstream archeology" can't explain the reality of the modern world either!
Where does that leave us? I don't know, but curiosity should be encouraged.
I watched some of the first season and was actually already open to all the alt archaeology stuff with the precision arguments people make, but the more I looked the more clear it was just BS.
I think the biggest thing about the old world people miss (and thus makes alt archeology so attractive) is the mass use of slaves and general lack of caring about human suffering.
I couldn't believe Red Fort was built in 9 years in 1640, until I had that epiphany, for instance. https://en.wikipedia.org/wiki/Red_Fort
You may need some evidence. For example, someone looking back on us might think that, because we accept the current level of suffering as normal.
What is alt-arhaeology?
We only need to go back 300 years to find the history we’re told isn’t reality. Do we think the Voc went silently into the night? Did the banking families of the 1800s reproduce to such a degree their fortunes are no more? We can keep going.
