All over the world we find ancient cave systems once used by ancient humans. Some are natural and others appear to have been dug out by humans. Some of these cave systems are very large capable of housing hundreds of people. The so called “mystery” has been “why where ancient people making and living in these cave systems for?”. So, what were they trying to get away from? Alien invasions? Global warming? Digging for gold?
It is my belief that our ancient ancestors (archaic modern humans and other hominids) were using these caves to survive the last Ice Age! It’s warmer underground than it is on the surface of the Earth. In some cases they used natural caves and in other cases they dug out cave systems. It was all about SURVIVAL and, indeed, they DID survive the last Ice Age. Had they not then YOU would not be here today! Think about it!!
So in my mind these ancient cave systems are NO MYSTERY at all. These are the places where our Ancient Ones survived! Keep that in mind my amigos!!
