Humans Were in America as Much as 21K to 23K Years Ago

In New Mexico some of the oldest prints in America indicate humans were around when prehistoric animals existed. Most of the times these groups migrated for food and resources. While we are more complex as a society we are often still very much the same way. The structures or our brains were developed during our beginning but we keep changing and adjusting as a species over time.

Human motivations are very much the same as they were in the past. We seek resources and in turn seek to find things that prolong our lives. 

Some are saying they couldn't have crossed the land bridge, some are saying they may have came by boats, and perhaps a few are saying they are indigenous. Humans Arriving in America. Considering that some of the oldest in the world are 233K Years Ago these prints would be seen as new comers.

Remember that science gives us data and we can draw theories but we can't say much precisely.
