In this video scientists explore underwater structures found off the coast of Okinawa. These Structures are under 40-100 ft of water. Scientists say the last time these structures would have been above water was 10,000 years ago during the ice age twice as old as the great pyramids of Egypt. During this period history tells us that the humans that lived at this time were hunters and gathers who did not have the kind of technology needed to build such structures. After months of study the lead scientist believed that these structures were 100% not made by nature and could only be made from an intelligent people with great technology.
