The pyramid was found in an area of the mid-Atlantic that has been underwater for about 20,000 years. Considering this is around the time of the last ice age where glaciation was melting from its peak 2000 years prior, whatever civilization, human or not, that was around before the ice age, could be responsible for building the pyramid. While the Portuguese Navy still hasn’t determined the origins, many might question why this hasn’t been first reported on sooner than late 2012. Certainly the NOAA who studies volcanic activity in the area of the pyramid would have discovered the pyramid through sonar imaging and so forth since the area is heavily studied due to volcanic activity. Either the NOAA hasn’t yet come across it, they are hiding what they have found, or the pyramid doesn’t exist. The last theory does not seem to be likely given the authenticity of the find.
