Unexplained Human History

Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?

Discover some of the most captivating mysteries of all time. Humanity has come so far and explored so much. As a species, we have more, or less conquered the entire Earth and all of its resources. We have built towering structures, intricate systems, and settled everywhere - from the tallest peaks to the deepest valleys. We have now entered what many like to think of as the enlightened, scientific era - where old superstitions and fears have been abolished, and the mysteries of the past have been solved. Basically, many of us like to think we have figured it all out.

How many worlds exist within the earth we see every day? Though there are many mysteries we cannot even imagine, the scientific discoveries and inventions of recent decades - along with myth, folklore, and various unexplainable events that have been recorded down through time - suggest to French scientist Jacques Bergier that the surface of the earth may be more complex, and its history more incredible, than is generally supposed.

When we look at the incredible feats of engineering that our ancestors were able to achieve, it leaves us in awe. Not just because these structures are beautiful and shrouded in mystery, but because they were constructed on a scale we can't comprehend, thousands of years ago.
