But religion might solve all your problems at the end of your life... if you have the right religion. Scientists aren't near capable enough to make science succeed for you.
That is the crux of the problem though. As you just acknowledged, it might solve your problems and it might not solve your problems at the end of your life. There is no way to confirm that your faith path is indeed the correct one, until it's too late. Even if supernatural being visits you personally, it could be a malevolent spirit leading down the wrong path...At least with science, we can always test and retests any ideas, and if we find some discrepancies, modify the ideas to conform to the measurements.
