Well you can, but that doesn't mean God will do it. You're asking a father, who loves his children, to remove their choice in the matter and force them away, despite him knowing it's better for them to stay.
Preface: I'm a Christian, so this will be about the Christian view on things. I can't really speak for other religions, since I don't really know enough about them.
On prayer: asking for miracles is not actually the main point of prayer, the main parts are listening to God, and God listening to you. Imagine a perfect parent/child relationship. Sure, there will be the occasional "hey dad, I need some money to make this month's rent. Can you help please?" or similar conversation, but most of the time it will be the child learning from the wisdom of the parent, or the parent helping the child vent. If you want to see an example of what Christianity says is the sort of things to pray, look at the book of Psalms in the bible.
On other religions: yes, of course at least most religions are fake. A false religion could be started by someone who believes they heard from God but got it wrong, or someone who wants to be the head of a religion for their own gain. Many religions warn about false prophets, so this is hardly a surprising thing.
Honestly I'd kind of like that in some ways. Language is actually pretty limiting, so not being stuck with it for thinking would make some thoughts easier to convey to yourself.
Why do we need custom backgrounds for our phones and computers? That's free space that could be ads. Especially good if clicking/tapping on the background causes a full screen, unclosable, unskippable ad. Because a misclick is definitely showing interest in the product.
Browser load times. Slow that down a bit, and you've got enough time to pop an ad in between every page load.
Only ea games I can think of that I've bought are jedi: fallen order and jedi: survivor. And I only bought them because they're actually good games that aren't monetized like a casino.
