They came to Earth thousands of years ago to usher in mankind's first New Age of scientific growth and spiritual enlightenment. Under the guidance of these ancient visitors from the heavens, human civilization flourished, as revolutionary advances in art, science and thought swept through the inhabited world. And they left behind magnificent monuments, baffling monoliths and awesome, towering structures that stand to this day as testaments to their greatness. In this so-called documented, meticulously researched work, Sitchin draws remarkable correlations between the events that shape our civilization in millennia past, pinpointing with accuracy the tumultuous beginning of time as we know it... Revealing to us the "indisputable signature" of extraterrestrial god indelibly written in stone.

 

OK, I had to include a Sitchin book, but please take his writings with care...
