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

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.

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

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

What is the kinkiest thing you and your sex partner have done in bed?

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

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

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?

How many boxes 600 x 400 x 200 go into a 20ft container?

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

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

THE BIBLE IS THE PROBLEM!

Why is our generation so unhappy?

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

A belief in a god is not the problem.

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

Why are US customs agents so talkative? I cringed hard when a US customs agent asked me if I was on vacation. He doesn’t need to know why I went to another country as long as I am a U.S. citizen.

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