Science has, arguably, improved our lives in very real and very practical ways. It's a bit harder to make that case for philosophy.
That's the problem with not being able to see outside of our reality. If our reality was just turned on a second before you made that statement, then for all considerations of our existence, science is at the exact same stage it was when you popped into existence with a complete repertoire of conjured memories. Consider what happens when you boot up a game and everything is pre-oriented as the game was staged. So too may be true for reality. Given that argument, maybe science has done nothing for us
