Could there be life on other planets?

Yes, there could be life beyond Earth, though nobody has proved it yet. Scientists look for places with liquid water, usable energy, and life-building chemicals. Those ingredients appear on Mars, icy moons, and planets circling distant stars, so the idea is serious science, not just make-believe.

The most likely neighbors would probably be tiny, hardy living things, not people in silver suits. Europa may have a hidden ocean beneath ice, and Earth has microbes that manage heat, cold, darkness, and pressure that would seem impossible to us.
