Why does it matter so much to atheists that God doesn't exis...

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?

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.

How do I stop someone from forcing/pestering me to become gay/bisexual when I already want to be straight?

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

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

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

Does the U.S military really prosecute military staff for cheating on their spouse, or do they close one eye if the cheating does not involve other military personnel since adultery is fairly common? Adultery is illegal in U.S military

THE BIBLE IS THE PROBLEM!

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

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

What is the word for truth and its meaning in Koine Greek?

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

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

A belief in a god is not the problem.
