Ancient astronaut theories are one of the most widely known theories about aliens. Throughout the 20th and 21st century a popular theory has been that aliens that have allegedly visited Earth have been visting for thousands of years and the theory goes that these "visiting aliens" were mistook for "God and angels" back in the ancient world, as they appeared to be divine beings which came down from the sky from what they believed was "heaven". Due to this strong possibility some believe that Alien encounters started off theories in the ancient times that there were divine beings who lived in the heavens above, so the question is could all of the bible have been influenced on this?
