Leah, In a way I think your right. I think that to a certain extent Area 51 is a big hoax 

HOWEVER!

1) Area 51 has been and will always continue to be a test site for spy craft.

2) Bob Lazar the name that put 51 and ufo's together never said the crafts were at 51 he said that they were at an area outside called area S4. I have seen the Majestic documentation that makes reference to area S4. Majestic was out far before Lazar was.

3) If the government were covering up UFO's and alien technology were do you think that it could do that best? At a remote facility like 51 or in an office building in downtown Cleveland??

4) Just because the Russians and the Chinese know about 51 doesn't mean they can do anything about it. and how do we know that the Russians and the Chinese don't have their own 51?
