To create the entire multiverse comprising several universes and our visible universe with 200 billion galaxies, each galaxy with 200 to 400 billion stars, each star with its planets and to create life on some planets, is a stupendous task for any creator. Such a creator cannot be a simple entity. It has to be a very complex entity.
We have seen that simple molecules combine to make powerful chemicals. Simple cells combine to make powerful life-forms. Simple electronics combine to make powerful computers. Logically, all things are created by a combination of simpler, less capable components. Therefore, a supreme being must be our future, not our origin!
And you know what?
If there is a God, and it's that same God who's so eager to have temples built in honor of his greatness, and wars fought over him, and people dropping to their knees telling him what a wonderful, magnificent being he is? If this all-powerful, all-knowing creature for some reason just can't get by without my worship? Let’s face it; God has an ego problem. Did he create us so that he will be always have some "captive slaves" to worship him?
One day, in my teens, when I was praying, it suddenly occurred to me that I was talking to only myself. There is no one there to receive my prayers. That was a revelation.
I realized that whatever we cannot easily understand we call God; this saves much wear and tear on the brain tissues. And "God only knows" that we need to conserve our brain resources to fight for our survival in this world, which is the top most priority for us. I realized that God for us is where we sweep away all the mysteries of the world, all the challenges to our intelligence. We simply turn our mind off and say God did it. God is an ever receding pocket of scientific ignorance.
Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is the belief in spite of, even perhaps because of, the lack of evidence.
If you're an atheist, you know, you believe, that this is the only life you're going to get. It's a precious life. It's a beautiful life. It’s something we should live to the full, to the end of our days. Whereas if you're religious and you believe in another life, that means you don't live this life to the full because you think you're going to get another one. That's an awfully negative way to live a life. Being an atheist frees you up to live this life properly, happily and fully.
What used to be 'demonic possession' is now known to be neuro-psychological disorders. What used to be 'divine wrath' is now known to be the Earth's geological and meteorological processes. What used to be 'curse' is now known to be microbial infections. What used to be a 'miracle' is now known to be a hoax. What used to be 'god' is now known to be an excuse to solicit money from ignorant people.
By all means let's be open-minded, but for "God's sake", not so open-minded that our brains drop out.
