I read the article.... it is an article about Marco Rubio (who, well...) saying he has "firsthand" knowledge of things; he said this, some people "high up" said that... it's a lot of "they said".
I don't doubt there is life in other planets (there has to be), and I won't discard the possibility of a civilization as we know civilization flourishing somewhere in a galaxy far, far away, but I have heard about evidence of UFO's/extraterrestrial life visiting Earth and government conspiracies covering up the possession of crashed UFO's and extraterrestrial technology for such a looooooong time, and I have yet to see the smoking gun. So pardon me for being skeptical.
