This was explained by countless theologians.
God's reason for existence is that God cannot not exist. God is necessary.
ipse dixit. Just because someone imagined a reason does not make that reason true. One could say the reason for yeti existence is because yeti cannot not exist. Yeti are necessary. You may substitute any fantastical creature. It will have the same truth value as your statement.
Atheism is just depressing and hopeless.
what makes it depressing and hopeless is being surrounded by brainless theists, knowing you will never see the preposterously stupid idea of god banished in your lifetime. Knowing that the majority of human animals will always be irrational chimps. THAT is what is depressing and hopeless.
I can't understand why anyone would want to believe in atheism over theism.
It is not a matter of want. It is a matter of acceptance. I do not believe in gods because I cannot. I have tried. It doesn't work. If you think you can, try believing the the Tooth Faerie for the month of March. Tell me how that goes.
I only want to believe what it true. Let us recite the Litany of Tarski:
If there is a god in the universe,
I desire to believe that there is a god in the universe;
If there is no god in the universe,
I desire to believe that there is no god in the universe;
Let me not become attached to beliefs I may not want.
I cannot understand why people would want to have false beliefs.
Wouldn't you rather have hope instead of darkness?
Not if darkness is the reality. Let us recite the Litany of Gendlin:
What is true is already so.
Owning up to it doesn't make it worse.
Not being open about it doesn't make it go away.
And because it's true, it is what is there to be interacted with.
Anything untrue isn't there to be lived.
People can stand what is true,
for they are already enduring it.
A. Your child is in Heaven with the Lord singing with the angels.
B. Your child's dead. You're never gonna seen him/her again.
Why the fuck would anyone say B? Do you think that is what atheists say to people?
And A makes as much sense as saying, "Your child is in the CandyCane realm, playing with peppermint kittens and chocolate dragons."
Wishful thinking does not cause reality.
