I think aliens exist on earth too, and in the olden days they were called demons. I would not like to be their Guinea pig.
There's a reason why you think that.
But the truth is that there are thousands of ancient texts that tell a different (but similar) story, than what eventually evolved into the monotheistic Bible made by the Jews. And what the ancient texts said, will blow your mind. The OT was based on these historical documents, and changed to become a monotheistic religion, to suit the plagiarists that wanted to make money and armies...
The original texts say something VERY different (but similar). Would you like to hear?
This is interesting, but wouldn't the original texts be destroyed thousands of years ago?
The original texts were written by the Sumerians 6000 years ago. Many of them still survive. Many others were rewritten by the Babylonians and Akkadians and Egyptians, so they continue on, in modified form. It's like the telephone game...
Since there were no copiers back then, things had to be rewritten, and often translated into languages and words that made sense for the culture at-hand. So the Sumerians wrote about the Anunnaki, and after 2000 years of retelling and rewriting, eventually culminated in the OT. But the stories are generally the same. It's the facts that are lost in translation.
And the biggest fact is that Anunnaki means "Those who came from Heaven to Earth", which means that they did not come from this planet.
