All 4000 of those planets have been established to have no chance whatsoever of harboring intelligent life. The charlatans have said stuff like "this one is 96% Earth like" while not mentioning the "other 4%" is something that totally precludes life. In truth they are less Earth like than Venus. Everything that has been found has shown Earth and our solar system to be wildly different than any other known orb and domain.
The stuff they are finding is really cool but it demonstrates what has been obvious for some time now,. Sitcom math is another demonstration of the same thing. The only case made for intelligent life existing elsewhere is "but there is so much stuff". It's too bad that "stuff" is nothing like Earth and than none of it has ever sent a signal.
