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.

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

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

Why did Kakashi use Chidori against Rin, despite knowing about her feelings for Obito?

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

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 are the potential economic consequences of the U.S. following Europe's lead on climate policies, as discussed in the article?

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

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

THE BIBLE IS THE PROBLEM!

Can people who have never met you tell if you are a covert narcissist?

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

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?

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

What do you think about Vivian Jenna Wilson's decision to speak out against her father, Elon Musk, in a public interview with NBC News?

A belief in a god is not the problem.
