Gods or spacemen?

About this book

If the literature of antiquity could prove that spacemen visited our Earth long ago would these wondrous revelation not transform the past, inspire the present, give hope to the future, bring new meaning to Man himself? Our religions, philosophies and culture were based on the belief that our world was the center of the universe and mankind the sole preoccupation of God. Would proof the Earth was once ruled by Beings form other planets not seem the fundamental discovery or our century?
