[PHC1]

If the topic of unidentified flying craft makes perfect sense today as we have something to compare it to such as our own flying objects, how does one explain the ancient, religious and even cave art depicting beings and craft of extraterrestrial origin? One can find evidence of that on every continent and every ancient culture. Where did they get the idea or inspiration to depict something that did not exist? Especially that it often matches the phenomena people witness in modern times?
