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

A belief in a god is not the problem.

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

THE BIBLE IS THE PROBLEM!

Why are there so many single moms in America?

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

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

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

Which is a better option, a love marriage or an arranged marriage in India?

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

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.

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

What is the most overrated pleasure? Why?

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

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

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?

What have you learned from your parents' mistakes?

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