Not long ago, the History Channel, through its show Ancient Aliens, made a remarkable discovery. It is a colossal pyramid hidden so far under the snow of Antarctica.

It seems that the authors of this discovery are Joseph White and his colleagues, who analyzed a series of satellite photos. At an initial analysis, this structure appears to be an artificial construction, the shape, and the right angles suggesting this.
Although Joseph White and his colleagues suspect that this pyramid was built by an extraterrestrial civilization, there is also the possibility that it was built by an ancient human civilization that lived in that area a long time ago.
But given that this pyramid has been hidden in Antarctic ice for over 12 million years, it is unlikely that humans built it.
