Conspiracy theory? Aliens?

In 1947 a UFO crashed in Roswell, they publically annouced it, it was in papers. Then they said oops it was a weather ballon, yeh right witnesses have come forward it was not some airballon, how stupid u think people are? There were Alien bodies found at the wreckage. There was another crash in 1949, with 1 surviving alien. A deal was made by the US Government to trade 'Technology' in return for the dead alien bodies. How do u think our technology has suddenly progresses so far in the past 50 years, we have been helped.
