A 3000-year-old spaceship-looking artifact is one of the most famous artifacts that supposedly prove the fact of the arrival of ancient aliens on Earth. Zecharia Sitchin was the first person that drew attention to it, having discovered the artifact in Turkey in 1973.
This mysterious stone artifact incredibly resembles a rocket with modern engines, in which a man is shown sitting in a spacesuit. It could be the ultimate proof for the ancient astronaut theorists that the otherworldly beings visited Earth in the distant past.
