because the natives have sued to disallowed DNA testing for the skeltons and remains found in the USA, the 'theories' that you present are speculative nonsense.
the facts are unknown, and it's highly likely that both Romans and Mongols made it to America far later than the numbers you show on your FAKE MAP.
The bricks of Mesoamerica are very roman.
the horseriding psychopaths (who invaded from the north and tried to enslave everyone) is very Mongol.
YOUR HISTORY IS FAKE
