The Ancient Lemuria

Do you believe there was an ancient civilization lost to us? What say you?
 
I made it half way thru this interview. There was no introduction but I gleaned that it was the grandson of James Churchward the occult writer from the early 1900s. It was a very slow and dull interview but an interesting topic. I lost interest when the guest (unnamed) admitted his grandfather lied about being a ranked officer in the armed services and was in fact just a fisher man. This put everything his grandfather wrote about under suspicion. The guest admits that his own father thought it was all made up. So after a while I just lost interest.

I do believe though there were obviously advanced civilizations that are lost in time. They left us the megalithic remains everywhere.
