This compilation of books all have an interrelated theme, which is that the history of humanity has been heavily influenced by aliens and alien technology.

The first book is titled Ancient and Prehistoric Civilizations. In this book, there are many ancient megalithic ruins of civilizations which push the frontier of our understanding of the origins of civilization by many thousands of years. Ancient giants may also have been involved in these constructions from the proximity of their remains associated with these sites.

The second book is titled Ancient and Prehistoric Civilizations - Book Two. In this book, I researched and found additional megalithic ruins, which also increase the mystery of who built them since many of these ruins must have been built way before the accepted start of human civilization.

In the third book, titled Strange Objects Which Should Not Exist, I did a review of artificial objects found with ages going back hundred of millions of years. These findings also include anomalous imprints of giants in rocks which are 100 to 200 years old.

Book four is titled Aliens Are Already Among Us. In this book, I examined how long aliens have been on this planet and how they have influenced us. My conclusion is that they have been here at least for many thousands of years and possibly much longer.

Book five is titled Aliens and Secret Technology-A Theory of the Hidden Truth. Here, much of our modern technology is researched and lots of evidence presented that much current technology and hidden super advanced capabilities have derived from alien discoveries.

Overall, this sequence of books shows that there is a theme throughout history that aliens have affected humanity, not only since Homo sapiens evolved but even well into pre-history to hundreds of millions of years ago, when animal life didn’t yet exist on Earth’s land. That giants lived on the Earth back then and had their own civilizations. Our civilization today is, in many ways, a result of our interactions of aliens for our entire history.
