I also believe that the US government are covering up the Roswell incident, but they would be too stupid to have their base at Area 51.
There is probably a military base in some desolate place (Canada,

) and they are still working on whatever they found at Roswell New Mexico, July 1947.
Also, the first microchip was created not long after the Roswell incident. Co-incidence?...I think not.
