There is an extremely high probability that Aliens exist despite the fact that there is also a high probability of many Alien civilizations becoming extinct by several natural causes. My guess is, we will start finding evidence of intelligent life once the E-ELT (Observatory) and the Giant Magellan telescope are built at or around the mid 20's.
The "Deep State" is very much a real thing and there is a lot of evidence for their existence. Hell, they don't even try to hide!!
