They gave their name to the Kofun period (middle 3rd century to early-middle 6th century). Many of the Kofun have distinctive keyhole-shaped mounds (zenpo-koenfun (前方後円墳?)), which are unique to ancient Japan. – Wikipedia.
The structure we see in Japan is unique, sharp edges and unique patterns define this incredible construction built in ancient Japan. But is there something more to this construction? Is there a small possibility that the structure found in Japan has a mysterious connection, a otherworldly connection perhaps? We believe the answer is Yes.
So what does NASA say about this finding on Mars? Well, according to them, these straight line and defined edges could be a result of fractures associated with faults or a hill that could have been raised by the fault. Its current shape is the overall result of the surrounding Martian terrain which has been eroded for millions of years. But is this explanation enough? We have seen quite a few unique shapes on Mars that can be traced back to similar structures on Earth.
Could this be proof that ancient mankind was in contact with extraterrestrial beings? Is it possible that millions of years ago Earth was connected to the red planet in a way that we today do not understand? We believe that all options are open for debate!
