Even if we find out Mars has always been lifeless, we’ll find it somewhere eventually. I’m also convinced we’re going to find something clearly alive (or that was once alive) that completely redefines our entire idea of life. Dunno what that could be, but like you said, every time we think something is unique, we find out it ain’t. Our definition of life is going to turn out to be too narrow, eventually.
It depends on time and distance. We may never find life, even if there’s a lot of it out there. This would be the case even if we had a lot of time and the ability to travel fast, but it is especially unlikely if we destroy our our capacity for technology through, for example, climate change-induced societal collapse or nuclear war. And that’s the road we’re presently on.
