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

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

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

A belief in a god is not the problem.

Sorry, Trump supporters, but eventually it will have to be asked: Why didn't Trump do as well in his first term as he is doing NOW?

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

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

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

I took a video of my serve (60 FPS) and it took 0.4 seconds from my racket to the service line. How fast would you say my serve was?

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.

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.

Were knights’ lances practical weapons, or were they just for sports?

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

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!

What does it mean when someone tells you they love you and want you in their life, but doesn't want to commit?

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