In 1938 archeologists in China discovered hundreds of stone disks in caves in the Baian-Kara-Ula mountains. Each one measured 9 inches in diameter and were etched with tiny hieroglyphics that tell a story about aircraft from distant worlds crashing in the mountains. They say the disks are thousands of years old.
I have a feeling that’s all speculation.
They simply haven’t haven’t found the turntable yet.
