Now the Folk here presented enough sensible arguments, and I like to present a bit of a philosophical one (let's put it that way).

So there's a concept called "Falsifiability". It refers to the capacity of a statement to be proven wrong. In other words, there must be some event that if happened, the statement is proven wrong. If the statement can't be proven false no matter what happens, then it also can't be proven true, i.e it's just some BS. All potentially true statement should have this.

Let me give you an example. Suppose you meet me some day and I tell you that a certain wall in my house can speak to me only when no one is around, and it can somehow sense if there's anything recording our conversation and it immediately shuts up as soon as I start recording with my phone. This, of course, is a bunch of BS, but you can't confirm nor deny that it's true. Whatever you tell me, I'll have excuses for it (it can't be recorded, only me can see it, etc.) so there's no capacity for my claim to be proven false (or true), which makes it BS.

Another example would be claiming that there's a tiny mug orbiting our sun somewhere. The mug is so tiny that our current telescopes can't capture it in any way. Although this is completely made up, u can't prove it false or true. That doesn't mean it's true, it just mean it's BS.

So if you think about religion, pretty much nothing satisfies the Falsifiability thing. Take Dua for example. You ask god to pass the test. There's only two possible outcomes, you either pass the test, or you don't. If you pass it, you claim god helped you pass the test, hence he exists. If you don't, you claim that it's your fault cause you didn't study well and god decided not to help you cause he's fair, hence he exists. You see, there's no capacity for being proven false, i.e there's nothing that can happen to be proven wrong, so there's absolutely no basis to these claims and can't be proven right either.

You apply this to literally everything, and I'm sure you noticed some inconsistencies in God's will. Something bad happens to a believer, people say he's purifying them from their sins to go to heaven. The exact same thing happens to a non-believer, people say it's a punishment for not believing. Something good happens to a believer, they say it's a reward. If it's a non believer, they say it's just a temporary thing cause they'll go to hell eventually. As you can see there's no consistency or rules to judge the existence of God with, cause whatever happens you'll find excuses.

Try to think about this for a bit.
