Iraq is something like a goldmine for the archeologists and historians since Al Ubaid archeological site is packed with many objects from the pre-Sumerian time called the Ubaid period (5900-400 B.C.).  The interesting thing about these ancient objects is that some of them are really disturbing and can even cause confusion. Many Ubaid statues represent creepy lizard-like humanoid figures in special but unceremonious poses which might indicate that they were not considered gods, but rather a race of lizard people.

These discoveries let people use their imagination and fabricate stories about lizard aliens who populated the world and perhaps still do (according to conspiracy theorists).
