The news would go nuts. It'll be all anyone talks about on social media and internet forums. Every comedian will have an alien joke. Books, movies, and games will be written about them. Talking about the aliens will carry the same sophistication as talking about the weather. Conspiracy theorists and the paranoid-delusional will confirm their worst fears and blame the government. The government will roll out a Department of Extraterrestrial Security and enforce more airport screenings. A lot of people would buy telescopes. Benedict Cumberbatch will act as one. Potheads will make first contact according to themselves. The stock market will go up (but I can't tell you why -- that's insider trading). People will do cosplay of them. People will draw porn with them. Xkcd will do a What-if and a comic or three. Python will add 'import aliens'. Silicon Valley will spawn at least 4 new startups related to speculative data machine learning about their browsing habits once we show them our internet. Colbert will do a special about being abducted and he never really wanted to leave anyway. John Stewart will claim that Fox News were aliens all along and this is the second wave. Fox News will find a way to blame Obama and John Boehner will finally shed his ninth skin. But that's just my take on it.
