I was just reading a post on climate change on another forum on this site. It was stated humans are the smartest species this planet has produced. I am not so sure.

There are anomalies in archaeological finds, some of which of questionable authenticity, that make me wonder at least if maybe Neanderthal and Cromagnon (sp) were not the only high intelligent, land-based cultures to live at the same time.

There was a map, which, if authentic, detailed the coast of Antarctica beneath the ice. It was supposedly made/or used in the 1500s. It was the nineteen sixties before this species managed to map Antarctica under the ice using satellites.

There is a Peruvian temple that's construction, if accurate to astronomy at creation, violates mainstream views on when Humans were in Peru.

And last, I will mention the Egyptians. What if the Sphinx has water damage? It would predate the Egyptians. Then there is the little issue of the Egyptians creating structures with ancient technology that cannot be replicated today.

If nothing else, it makes me wonder.
