"These strange underwater pyramid structures at a depth of two thousand meters were identified with the help of a sonar according to oceanographer Dr. Verlag Meyer. Studies of other structures like Yonaguni in modern day Japan have allowed scientists to determine that the two giant pyramids, apparently made of something like a thick glass, are really impressive - each of them is larger than the pyramid of Cheops in Egypt."

That's some sonar that can tell that it is made of glass and is translucent.

Smells like something from the bull backside to me.
