As a scientific curiosity, there most likely is other life, and it would be interesting to find evidence of it.
In reality, we will never get beyond that. The limits of the speed of light makes going to observe life on another planet almost impossible. Even if life is found on a planet orbiting the nearest star, few people would be willing to go there because of the length of time such a journey would take. Preparing for such a journey would be prohibitively expensive, as well. If intelligent life that can communicate by radio is found, we may be able to exchange messages—but how will we reach understanding of them?
I love when people bring up the “speed of light.”
We’ve been going to space for about 50 years now. There’s alien races that probably have been going to space for as long as we’ve been around as a species. Who knows what kind of propulsion systems they have? It has to be much better than using chemical rockets to break free of atmosphere.
I’d guess aliens don’t consider us worth the effort to contact because we’re so primitive.
