What are the chances we (as a species) make contact with aliens within our lifetime?

>Because why would they?

All the wrong reasons

How would they?

As in, how would they know we exist?

Assume, a technologically advanced alien race lives withing 200ly of Earth (highly unlikely).

Well, if they were scanning 100% of their sky, they would just be hearing our first (very weak) radio signals. Is it possible to tell that these now redshifted signals aren't random noise? Probably, but it's not like they have Radio Aerials, or would understand human speech in the first place. And if they're just recieving the signals now? It takes at least 200 years for them to respond. If this species is scanning even 90% of the sky, it is entirely possible they missed us, the sky is very large.

Anything outside 200ly radius? Doesn't have the possibility of hearing from us yet. Wouldn't know we exist.

>100ly radius

>chances

chances are very little:

"You know, we've disguised ourselves as extraterrestrial visitors so as to not alarm people with what's really going on." -- The Contact

>we've disguised ourselves
That's going to alarm people a lot more than just being honest and open would.

Maybe the mental climate is slowly changing, but those who know about the ET presence still follow the recommendations of the Robertson panel: Coverup - Denial - Ridicule. John Podesta currently plays the role of a trial balloon regarding a 'limited hangout'.

He's been posting it in tons of threads for some reason.

No, the best we can hope for is discovering evidence of their existence. Well, I suppose the best we could hope for is like some gas station rest stop scenario like in Rendezvous with Rama.
