Twenty-two years before Technology of the Gods...Seventeen years before Fingerprints of the Gods... Fifteen years before Forbidden Archaeology... ...there was Worlds Before Our Own, Brad Steiger's groundbreaking argument for the existence of a global prehistoric civilization. The evidence Steiger had amassed for such a claim was based primarily upon finds of "erratics" -- mysterious "man-made" artifacts found in the deepest, most primordial geological strata. In the past couple of decades the concepts first presented in Worlds Before Our Own have garnered tremendous critical and popular support. This is the book that started it all.
