You will never meet anyone from another solar system. Even if we assume such life exists (it might or might not - either is extraordinary), there is every reason to believe it is far away. It would be extraordinary again if that life is close enough to earth that the round trip of a radio transmission is within a human lifetime. There are just a few hundred (I wasn't able to find an exact number) starts within 25 light years - 50 year round trip time for a radio signal. We know of hundreds of earth like planets, but only by a definition that includes mars which is pretty much dead.
