People decide not to believe in God, and yet they believe in Quantum Mechanics. Why?

The difference is that there's an overwhelming abundance of evidence for quantum theory.

Entangled particles are pretty crazy, but it turns out that they actually do behave in those ways. Bell's Theorem rules out the possibility of hidden variables, so they actually are somehow acting nonlocally.

And it doesn't require abandoning logic. Logic is based on our intuitions about how the world works. Quantum particles behave in nonintuitive ways, and one simply needs to accept that our intuition doesn't apply in certain cases.

No, you're missing a large difference. I can review quantum physics research and verify that it is supported by evidence, and I can evaluate the models and formulas that support it. I can also verify that other, creditable professionals have reviewed it.

On the other hand, when I look for expected evidence of God, I find that life evolved, that there is no evidence of a global flood, and that the exodus never happened.

The other major difference between quantum physics and God is that I do not believe in quantum physics, it is just a branch of knowledge to me. In other words, I realize that what we know today may be changed as we learn more, which is the nature of knowledge. Belief mandates that it's knowledge stays the same and that new information that discredits the belief is wrong.

Edit:

Logic is a very specific study and while it is related to science, about the only ones that it is really useful in is Computer Science and Mathematics.

Sorry, I can't quite explain this well, but here goes: When trying to determine if God exists we have several paths or methods. Using logic (the weakest path), we can examine the claims made for god and those against. An example of this is Pascals wager; it sounds reasonable until you realize that around 4 billion other people could say the same thing about their specific gods. I guess the reason that logic is a weak method is that it is highly dependent on the amount of knowledge that is available. For instance, it is not logical, especially under christian views, that some species mate once and then die, however, understanding that the only purpose of life is to reproduce makes this more logical. In this sense, Quantum physics is only illogical until you understand it. On the other hand, there is nothing logical about God, even when you understand him.

Because there is more evidence with Quantum theory then there is with a belief of the invisible man.

God is not logic god is faith.

Science is logic and years of testing and research this can be proven the other cannot.

Quantum computing is 10 years or less away.

Having taken graduate level courses in quantum mechanics I can tell you it not only makes sense but it is supported by vast amounts of evidence. God isn't.

I will tell you that everything is extremely intuitive when you understand QM. You don't abandon logic to understand QM but you do need to apply logic in ways that may conflict with some of your naive assumptions.

Quantum Mechanics to me is not only obvious but it is a necessary consequence given nature is vast and diverse and that our concious identity corresponds to the algorithm the brain performs and not the brain itself. Much like Microsoft Windows corresponds to what a computer does and not the computer itself. Quantum uncertainty derives from the uncertainty in principle of determining which brain (of many ) your mind is executing on. Quantum Collapse corresponds to mind algorithm splitting. Entangled particles are merely correlated with corresponding brain algorithms. The fact reality is multivalued neatly avoids any conflict with Bell's Theorem.

The problem with explaining this to you is that for you to understand it I would need much more time and you would need much more mathematics.

"Any sufficiently advanced technology is indistinguishable from magic."

God belief is the refuge of the intellectually lazy.

I never "decided" not to believe in god but I cant even imagine that there is one. Even when my parents took me to sunday school as a child I looked at the teacher and the preacher like they'd been sniffing glue when they quoted the bible. None of it ever made sense to me that I can recall. And I still know nothing about quantum mechanics. To believe in anything in spite of evidence to the contrary is diagnosed as delusionary in psychiatry.

If you understand the math, QM doesn't require "belief".

If you don't, then it sure does.

QM can be pretty funky (ie spooky action at a distance) but it makes much sense and IS logical if you can understand the math around it.

There are several books out now that can help in that area if you are interested.

I don't believe in God, and I don't remember ever telling you that I believed in Quantum Mechanics.

I guess I'm not allowed to have a choice to say neither?

are you serious. science is all about attempting to understand and quantify the world around us. quantum mechanics is just another area of science, still relatively new, that is trying to explain things we do not know. it is completely different than blindly believing in god,

To understand this, you need to familiarize yourself with the scientific method as a foundation for determining how the universe works.

Logic, reason and rational thoughts have shown me that god does NOT exist.
