Should you go to Mars? ft Bill Nye

I never understood the argument; "Life on Mars would change everything."   Why?   They say because "we would know that we were no longer alone in the universe."   But so what?  We are not alone *on Earth*, including places so hot, dark and under so much pressure, they might as well be an alien world.   So does it really fundamentally change anything to know that some other exotic location, albeit further away, has or had life?  Sure, there would be religious implications for some, xenobiology would explode, and there would be renewed interest in space exploration in general.   But change "everything?"   

Of course this would be different if *intelligent* life was discovered, but fossilized microbes or jellyfish are not going to make pie any more delicious, or your bills any lower, or delays at the airport any less frequent, in and of itself.
