I hate to be the lone voice that tries to explain this away but most of the mounds are volcanic fissures. If you go there and look at the rocks they are volcanic in nature. Most of the watering holes the guy shows are quite common in central and south America and most of them are sinkholes. Some of them extend thousands of feet down.
Something else to consider is that we have known about Mammoth Cave for hundreds of years, and the natives knew about it far longer. So why don't we know anything about it? Why are they hiding the branches that go down into the hot depths of the crust or extend as far as Texas?
Why do they call obvious manmade structures natural? Why do they hype some things as manmade but not others? Things to think about. Take this with a grain of salt, big-time. Any theory that postulates a prehistoric civilization is 3 AM history channel stuff.
