Proof at Last. This is the story of one man's impossible quest to prove the impossible, to provide evidence, acceptable to legal standard, that alien beings once walked the face of our planet. From an entirely logical reassessment of the peerless work of Sir Flinders Petrie, founder of modern Egyptology, a hypothesis was born and a theory developed. After almost 50 years NASA has at last demonstrated the technology that made alien contact possible. The final proof is that, brought up to scale, this technology matches in every meticulous detail the pyramid launch sites all over our planet that used beamed microwave and/or solar energy for global transport and space access. This may be the most important book you will ever read, the one that reveals the answers to man's oldest and most enduring quest, to know where we are from and where we are going, and how.
