What if life actually started on Earth and found it's why to Europa due to meteor bombardment on Earth before the dinosaurs. Wouldn't you like to know if you have neighbours and if those neighbours are related?
Just remember that wifi that you most likely used to post your comment was created by Astronomers to do obscure star stuff, and it netted CSIRO 450$M of royalties, because it changed people's lives. http://www.theaustralian.com.a...
The internet itself was "something that won't change anyone's life" when it was built in the 1970's.
That is what basic science is all about. Discovery for curiosity's sake. If your child is dying of zika or malaria or ebola and a cure is found you might be grateful for the scientist who stumbled upon the answer by doing something completely different, or because they used software built by geologists or astronomers. Astronomy has also influenced cancer research, because software to identify stars can also be used to identify tumours. Astronomy is always valuable. New weather satellites that will better predict storms and flooding will save many lives in years to come.
The poor country Bolivia now has a satellite, https://en.wikipedia.org/wiki/...
, which enables Andean farmers to communicate with each other and their markets - improving their personal income by helping them bypass expensive middle merchants.
I challenge you to compare your own country's research spending and compare it to spending on pet food or candy. You should be horrified at the result.
