As far as I am concerned,it is really vested interests who say we must look for other life in the universe, I think the general public wouldn't give a damn,but scientist and Astronomers accentuate it so much that it is given that it is so important to the human race,which in real life is not.
Keeps people in a job and the likes of universities sound that it is important.
More effort should be made in sorting problems here on Earth than spending billions on looking for life on Jovian moons.
It is exciting to do planetary exploration, but the guise of looking for life in the solar system is a waste of money.
Just my 2¢ worth.
