Why does it matter so much to atheists that God doesn't exist?

These are man made rules - made thousands of years ago for the use of the humans who lived thousands of years ago.

Notice that I said their rules, not any gods rules.

And then use and ENJOY these fantastic scientific advancements every single day of your life?

What is a good tool for product analytics besides Google Analytics?

And how do you deny hundreds of years of advancement in all fields of science?

I do not personally care if you believe in a god or not.

THE BIBLE IS THE PROBLEM!

Should parents be allowed to bring children into R-rated movies? What are the potential consequences of doing so?

Because these are not any gods rules we are talking about.

Those rules that you are trying to reinstate are rules made by men who didn't know anything about the earth, nor anything about all of the other inhabitants of it. How can you not see that?

My problem is that people who try to shove their rules down everyone's throats - including by physical force - DO EXIST .

Why don’t people want the American Dream anymore - marriage, kids, a dog, and the white picket fence?

The people of the modern world have evolved past all of that nonsense.

IT does not matter, mainly because it does not exist.

A belief in a god is not the problem.

Have you ever had a scary dream about a loved one or friend soon after their death?

I am speaking to the US Bible thumpers here, of course ~ many of whom are flat-earthers who deny evolution and see scientists as evil people who are constantly trying, and succeeding, in disproving their beliefs one by one.
