22. The Ubaid Lizardmen
The Ubadian culture lived in prehistoric Mesopotamia around 4,000 BCE, and they were relatively advanced for their time. Of the artifacts found, the Ubaid Lizardmen still perplex archeologists. They are all statues and figurines that look like lizard people. What they represented is the key mystery. Some say they represented their gods, but this has been discredited by archeologists, saying the posture is different than usual ritualistic artifacts.
