Unfortunately I’m on the side of: space is so unimaginably, incredibly, excessively, large that no other intelligent species is even remotely close enough to us to ever have the hopes of interacting with us. The best hope we have is finding “bacterial” life on another planet/moon here in the solar system.
That distance exists not only in space, but most likely time as well. Extrapolating from our singular data point, it would seem that the lifespan of a technological civilization is quite short. The odds of two of those being around at the right times for even one of them to detect the passing emission shell of the other is diminishingly small.
Even if they could reach us from some far-flung star system. There’s no guarantee that we would be able to even communicate with them. For instance ants use pheromones to communicate. There’s no way we could understand pheromones. We still can’t talk to dolphins. The other problem, generally when a civilization comes in contact with a less evolved civilization they tend to wipe them all out.
I think I’ve seen calculations that we could explore every star in the galaxy with self-replicating probes in something like a million years; and other civilizations could do the same.

Stupid physics… :(
