A hands-on archaeologist. Jonathan Gray has traveled the world to gather data on ancient mysteries. Over the past 48 years, he has penetrated some largely unexplored areas, including parts of the Amazon headwaters. He has also led expeditions to the bottom of the sea and to remote mountain and desert regions of the world. His findings include evidence of ancient Egyptians in the Americas, remains of ancient giants on a remote Pacific island and of Egyptian chariot parts and skeletal remains scattered over the seabed. Jonathan has published more than 50 books and videos, written several hundred papers, and hosted newspaper columns. A controversial, highly sought after speaker, Jonathan has appeared on numerous television and radio shows worldwide, and lectures to audiences on every continent. In the course of his explorations in more than 30 countries, Jonathan began to uncover evidence of surprising “out of place” artefacts that simply should not exist! There was a global pattern to them, suggesting an ancient worldwide civilization of astonishing proportions. This compelled him to write Dead Men’s Secrets, and more recently Dead Men's Secrets Update, which catalogue more than a thousand evidences of a lost super science and technology… including dozens of achievements ahead of our day.
