Are aliens science fiction or science fact?

They are a fact. I have spoken with them and seen their ships. Many many people have met them and we report this all over the media and internet but still people don't believe us. The number of people who know is growing steadily right now. According to the alien I talked to, they can see many times further than we can with their telescopes and he said that they know of many many times more galaxies than humanity knows of.
