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.

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

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 .

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.

Could humans be selectively bred, like dogs, to create 2 subspecies that can no longer have offspring? Do I not understand selective breeding properly? Im not worried about the moral implications, just the science please.

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

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

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

Has anyone ever participated in a gang bang and what was it like?

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

THE BIBLE IS THE PROBLEM!

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

Why was Super Buu so afraid of having Fat Buu torn out and becoming Kid Buu if he was going to destroy the Earth even before his transformation?

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?
