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 BIBLE IS THE PROBLEM!

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

Why is Prince Harry being fired by BetterUp CEO Alexi Robichaux, and what role did Marc Benioff’s decision to pull sponsorship play in this?

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?

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?

Can you name an example of bad parenting?

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.

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

I am skinny, I have been doing 100 pushups a day for more than a month and am seeing very few results, everything is so unfair, I workout more than anyone I know and am still skinny, why cant I build muscle?

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

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

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

Why do people turn a blind eye to bad behaviour if someone is very good looking? Whereas if someone is ugly, they get harshly judged for everything?

A belief in a god is not the problem.
