Publisher's Synopsis
When we consider the span of 300,000 years that Homo sapiens have walked the Earth, it's mind-boggling to think how much history could have been lost in the depths of time. It is entirely possible, even plausible, that civilizations far more advanced than our own once thrived before the last Ice Age. These societies, existing tens of thousands of years ago, may have developed technologies, cultures, and religions that rival or even surpass those of our modern world.
