Spiritually speaking: If God exists why does God exist?

My guess is that he evolved on Planet H. --- A planet which formed shortly after our Universe was formed 13.7 billion years ago. -- A planet that is now more scientifically, technologically, and evolutionarily advanced than Earth (which formed only 4.5 Billion years ago).

You are confusing a proclivity for homosexuality vs. the act of homosexuality. Let me take an analogy. Why is it that some people are alcoholics? As I understand, part of this is a genetic issue, a disease. However, the bible doesn't condemn alcoholism, just drunkenness. So some people have a proclivity to "get drunk" but don't act on it. Where then is the condemnation? Part of the proclivity is a result of us living in a fallen world with sinful nature. That may not make dealing with the issue any easier, "But thanks be to God! He gives us the victory through our Lord Jesus Christ." (I Corinthians 15:57) I hope this helps answer your question.

God exists only in the minds of the faithful.

There is no why, the Creator just is. S/he manifests as all that is. Your question is located within the false paradigm that God/dess and we are separate. There is only one God but there are many Gods. It's a paradox you can never work out but you can recieve and experience. No Bible or any other scriptures will give you this experience, it is a Cosmic reality. We are God.

God exists because god exists. Haven't you ever talked to a theist before?

God is the reason God exists. Look at NewAdvent.org/summa and you will find the answer.

people think he exist so they arnt afraid of there not being a god. the people who do believe in him need something to worship because there to mindless to think for themselves

This was never explained in the book. Maybe it will in the sequel. Anyone know when It's due out?

He's got nothing better to do.

What?
