A Theory of Ancient Prehistory and Giant Aliens

I have written six other books on ancient civilizations and Giants. This book ties them all together to show that these ancient societies and relics had to have been created by Alien Giants who existed not only during human history but millions of years ago. Many pieces of evidence are included here to provide evidence for this claim. Some newly found information is also included about these ancient sites including wheel ruts millions of years old.
Evidence is shown for Giants on this Earth not only during recorded human history but millions of years ago. The Lena Pillars are also reviewed to show that this might have been the main city of an ancient civilization over 500 million years ago and the source of the Hyperborian legends. Many ancient megalithic sites which are so old we don't even have potential ages on are described to show that they are real constructions and must have been part of ancient societies.
The evidence for truly ancient sites and relics exists. It just needs an overview and theory of how they exist and why.
