Why Would Area 51 Build A Pyramid ?

In past we reported "Pyramids Globally Beaming Energy To Mysterious Space Cloud". Now in another interesting development Google Earth reveal giant Pyramid near Area 51 base.

Why have they built a gigantic pyramid like structure there in Area 51? Is Area 51 trying to harness mysterious ancient technology?

Is this MORE PROOF of ‘alien technology’ here in America? Something strange is certainly going on and for some reason; our own government doesn’t want us to know about it.
