If I were to become an atheist...

How long are you going to keep up this bit of nonsense? All beliefs are not equal. All beliefs do not require "faith." Believing the sun will rise or explode tomorrow are both beliefs, but one is based on reason and the other is based on nothing. Trying to pretend that they require the same level of faith in order to believe is just wrong. Similarly, belief in science exists because the proof science works is all around us. It's present in the very machine that I'm typing this reply on. Every time I open my icebox, drive in my car, talk on the phone, flush a toilet, play guitar, watch a movie... what can you do these days that is not a reminder of the triumphs of science? So, believing what science says is a direct result of science having proven what it says it knows is true.

If religion had ever done this, religion wouldn't require much faith either. If faith healers had as much success as doctors/modern medicine, they'd be as wealthy as doctors. Plus, if any religious believers could walk on water, raise the dead, or do half the miracles in The Bible, we'd also believe what they said even if we couldn't do what they did. There's a RATIONAL tendency in humans to believe in things that prove their correctness, even if we can't produce the same proof ourselves. This shouldn't be conflated with believing in things that provide absolutely zero proof, or evidence of any kind, that they're true, which describes all religions.

This is one of the truest things you've ever said. You've just described "god of the gaps," and pretty much explains ALL belief in God (not just some). Looking historically, how successful has using God to explain unexplained phenomena been? Lightning? Rain? Earthquakes? Sickness/Disease? Seems like it's batting a perfect 0.
