The Mayans do exist today. There are a lot of Mayan descendents in Mexico still to this date. We had a tour by one and he was extremely knowledgeable. We got lucky on our tour. I was in Cancun 2 years ago and we went to the Chichen Itza ruin. It was truly a wonderful place to visit and learn about their culture. They were extremely advanced for their time. Their acoustical understanding was amazing. You can clap your hands in front of the temple at a specific spot and it makes a noise of a bird. They also had ball field that you can whisper on one end and hear it on the other end. Pretty amazing stuff.

As far as their end of the world, it's a bunch of hype that modern wackos were hoping would happen lol
