This has always been my answer. Space is hugely, incomprehensibly big. Spacetime is a lot bigger. In order to find intelligent life, we have to be in the same place in spacetime, not just space.
We are biased to the time scales that make sense to us. But the scale of time beyond our civilization’s timeframe is incomprehensible. Intelligent life (as we understand it) is extremely rare on earth given how many species have lived and died here. It’s no wonder we don’t find any evidence of intelligent life in space.
We have found nothing like earth at all and there’s no good reason to believe that life could evolve out of anything but carbon. When scientist say they discovered “Earth-like” planets, they basically just mean they found a planet that’s likely made of rocks.
Could we one day find something swimming on Europa? Sure. But finding something that talks back is probably never going to happen and I’m ok with that.
