In my view, the Milky Way galaxy (let alone, the entire universe) is far too vast for me to assume that we, on this smallish mudball, circling a second rate star, in the hinterlands of an unremarkable collection of stars, are the one and only form of intelligent life there is.
There are two hundred BILLION stars in our home galaxy, and even more galaxies in the the observable universe. The staggeringly incomprehensible numbers involved, lean towards a universe teeming with life - advanced and otherwise.
At some point, we’re going to tap into a signal from one of them, though I highly doubt it will be anywhere in the radio spectrum, which is much too slow for interstellar communications.
So we're talking subspace channels here?

To counter those big numbers, the available evidence points to the probability of life, especially intelligent life to be extremely small.
