There are those who believe that embedded in our most sacred religious texts, as well as in the design and location of ancient monuments, are secret messages–messages that may reveal the purpose behind our very existence. Could it be true? Strange and cryptic communications with unknown meaning have been discovered all across the globe throughout every known civilization. Might the key to unlocking the mysteries of the universe be found hidden in numerological, geometrical, and geological puzzles left for us to solve by extraterrestrial beings that came to Earth thousands of years ago? Are humans being tested? Have we learned enough to crack the codes necessary to decipher these messages? And if so, might our understanding of them allow us to finally be reunited with our celestial ancestors?
