It is not prehistoric. It is historic. History was already being recorded for 10,000 years before this was built. Even in the west, tribes were recoding their movements, travel, encounters, and civilizations. It is not prehistoric.
I noticed how they say thousands of years old and then quickly say 7 hundred years old. This looks way older than 7 hundred years and I can almost guarantee that this was inherited by these traders not built by them.
@@Tijereño Yes. What's your point? My point is that European civilizations were considerably more advanced in most respects, and their achievements dwarf those of the native Americans.
