One of the toughest things about being an archaeologist or scientist is accepting that there are things that you'll never know. Every discovery you're about to see in this video has been observed, tested, and considered by some of the brightest minds on the planet, and yet those bright minds have been forced to concede that they don't understand them completely, and they probably never will. They're archaeological finds that have kept their mysteries, and we're excited to show them to you!
