Human Footprint

This human footprint was found in a permian period (248-290 mya) rock. According to evolutionary theory, the first humans did not evolve until recently, approximately 100,000 years ago. Also found in this permian layer were many large mammal tracks which did not evolve until the Tertiary Period (54-65 mya) according to the Geological Column.




Conclusions:

In Progress
