It would be honestly cool to discover other life forms on another planet. However, I find it unlikely it could ever occur during our lifetime. Speaking my age, I have plenty of time left but I am not sure of those who read this and how long they have to live as an individual.
I also find it highly unlikely that we will discover planet(s) we could create a habitat out of and live successfully during our life expectancy.
