There's a story about the devil having a breastplate made of gold that was left here on earth when he came from Mars. Supposedly, this is the origin of the GOLDEN FLEECE story. Ares, also known as Mars, was associated with a golden breast plate as well and was said to traverse between earth and his home via some sort of door or gate. Many have said that it is probable that Mars was the home of fallen beings who travelled to earth via a stargate. It is indeed farfetched but considering that all of these old stories are the same: Ancient God from another world, comes to earth, loses armor, returns home without it, valiant heroes go in search of said armor to give to an opposing god, etc.
Maybe all of these stories have a common root somewhere.
