Just found out about these cool stone disks supposedly discovered in a cave in China that are purported to be 12,000 years old, called the Dropa stones, which have fine spiral grooves carved in them, and look like records, but they discovered that they are covered in tiny hieroglyphs, and eventually decoded them to uncover a story about how supposedly a group of aliens came from space, crash landed in those mountains, and hid in caves there, because neighboring tribes tried to kill them. Supposedly, the descendents of these aliens, the Dropa people from that region are on average 4 feet tall, with big heads, weird eyes and yellowish skin, and do not fit the genetic characteristics of any other races in the region.
