Mystery Pyramid At Area 51 2013

The secret base at Groom Lake, Nevada also known as "Area 51" or "Dreamland" has a massive Pyramid, but why?

One can only speculate on its purpose but it is reasonable to assume its not just for decoration.
Many have speculated that Pyramids could be ancient Alien conduits, able to harvest immense electrical energy from the ether, and transmit it to Motherships or even perhaps across the void of space.

Pyramids are still being discovered all over the world, from the Artic, Tibet and China, to the the deepest jungles of South America, some have even been found on the ocean floor.
The only question is who really created them and for what purpose, maybe we will never know.
