There is an Area 51 and it is still very active. I have been there many times.
Yes, the Aurora is real and yes it is fast according to you people. I contributed a lot of the technology to it as you humans had it all wrong. The supersonic drives on the Aurora are actually pretty primative by my standards, but they work quite well.
Yes, there are "alien" remains and space ships in Area 51. They are all dead. Every time the US Government picks up another one, they call me up and I go kill it for them so they can study it indepth. Since I have traveled the universe I can identify the different life forms very easily and tell scientists where they came from.
There are a few "lonely" scientists out there that have had sex with alien corpses. One time I went in and tied a live one down and they ran a train on it. It was funny though, because afterwards I told them they fucked a male alien and not a female alien.
