Aliens existance is confirmed by NASA

It is always believed that there is existence of aliens. But from where do they come from is still a mystery. Recently an alien ship was found in south of Las Vegas near Needles California. People near the place who witnessed the Alien ship says that it actually crashed west of the Colorado River. And NASA authorities had immediately arrived to the spot and moved all the parts of the crashed Spaceship to their research area. Initially when the people saw spaceship, they thought it was a meteorite which was because it traveled at a very high rate of speed and then slowed down just before speeding up again and then disappeared behind a hill where it was assumed to have crashed just out of site from witnesses.
And still NASA haven't provided any information about this and maintains the secret. It was assumed that NASA preventing people from knowing about these Alien related things before they confirm anything firmly as a proof for existence of Alien. But its a well know fact that two intelligence exists within our universe itself, one is us plus the other is what under investigation. But there is firm possibilities that several intelligence can exists in other universes that are far from and parallel to our universe. How ever still things remains mystery.
