Hey, I'm a newbie so can someone answer me this: if we find a signal that means intelligent life out there, just how OLD will it be?

Guess we wont know till we find them first. We will need to find out how many light years away they are and then take a big guess on how long they have been around.

So, presuming they come from a different sun's system ie not sol, say, even the nearest star, what is it?(alpha centauri ??) If it came from a planet around that star, what would the message's age be?

If the signal travels at the speed of light from Alpha Centauri, I'd say about 4.2 to 4.8 years old... Could be more if it is a continuous transmission...

Anything else that I have yet to factor in....? could be longer...
