Why does God get the credit?

[mordant]

Why give God credit though? 1 Corinthians 10:31 "So, whether you eat or drink, or whatever you do, do all to the glory of God"
Prayer helps tons of people. Even if God weren't real, prayer would still be positive affirmations and a way for people to self-talk through their problems.
Belief helps everybody, you believe everyday that the force of gravity will hold you on the planet. You may not want to look at it like that, but you sure act like you have a lot of belief.
Let's pretend you meant faith there. faith helps people to. Faith builds hope which is helpful in breaking away from negative feedback loops. Faith also develops positive goals, goals that people use everyday to achieve their desires.
You may consider thanking God is stupid, but that's because you're not convinced He is real. There's not really any harm though in acting like God is real and thanking one extra cause for your "blessings" is there? It doesn't diminish the thankfulness in any other cause. I think you have a zero sum mindset regarding thankfulness, and I don't believe you're correct on that point, IMO.

It depends on how the cited verse is interpreted / understood by particular believers, but literalists would say ALL means ALL. God gets ALL the glory for the things YOU do, even though it was YOU that did them. By extension, the surgeon doesn't get credit for saving your life, that would be ungrateful towards god.

I realize of course that many Christians -- arguably, in practice, most Christians -- don't consciously take it to this extreme. However ... many in my experience and observation are so conditioned to reflexively give thanks to god for both the sublime and the ridiculous, that they do have a tendency to attribute far more to divine intervention on their personal behalf than is even remotely warranted. Indeed, the canonical example of praying to god for a parking spot or to locate missing car keys and then thanking him for the parking spot or found keys or the won ball game or whatever, strikes me as an effort to claim prayer was answered in any way possible. If they would stop to think about it for like three seconds I think they would have to admit that unbelievers and heathens find parking spaces and missing keys at about the same rate. But they NEED to be able to claim victory because the truth is, prayer simply does not actually work.

Athletes "giving glory to god" for winning a game is the height of this lunacy in my view. Things like that have, all things being equal, a 50% chance of coming true all by themselves, and if you know you're a more skilled / practiced team than the opposition, asking god for victory after stacking your own deck strikes me as a pretty desperate gambit to claim prayer is effective by people who know full well on some level that prayer is bullshit.
