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

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

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?

Can AI kill MBA jobs even if MBA is done from Ivy league universities? What should one pursue AI/ML from IIT or MBA from IIM in terms of better opportunities/wealth and career growth/duration?

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

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

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

THE BIBLE IS THE PROBLEM!

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

A belief in a god is not the problem.

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

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

Is it wise to choose your family over your honor?

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