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 BIBLE IS THE PROBLEM!

Have you or anyone you know invested in cryptocurrencies before? If so, which one did you invest in and how much profit did you make?

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.

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

Why is the word "democracy" not in the preamble of the US Constitution?

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?

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

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

What is a good investment portfolio for someone starting in their 20s? 90% VT and 10% BND for a Roth IRA then 100% TDF for a 401k?

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

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

A belief in a god is not the problem.

What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

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