Possible Sumerian connection with aliens

Sumerians were one of the most advanced civilizations that existed on earth.

We are thanking them to develop one of the first uniform writing systems. Plus they not only left us with their writing system, but They also stunned us with their carvings on Clay, Stone, Metal, and wax.

Their carvings provided us with information about how they lived and how their culture grew, but Some carvings put us in a dilemma because they point towards some extraterrestrial beings that could have been present in that era.

In this photo, An obvious giant is shown who is either teaching or ordering to operate something on table. It could be sun or the back portion of a capsule.
Lots of theories are presented for this specific photo.

What are your theories for this???

Astronaut Carvings found in various sculptures from various time period.

How?

You read the heading and might probably be thinking about how the hack the ancient people knew about the exact shape, size, and types of equipment needed for space exploration. 

Right?

Here are some of the carvings from all over the world that resemble the modern-day space explorers. Could it be possible that they watched the people coming and going into the space wearing fancy dresses? and because they were not able to understand what is going on they just made it into the art form so that people in future generations can decipher it?

The Sculpture from left is from the Aztec community and Photo from Right is from Russia taken in the 20th Century.

The Sculpture from Mesopotamion period clearly connects some dots.

Wait, let's Compare other Images.
