The Many Things God Hasn't Done
No doubt there's some important stuff I'll have missed; feel free to add to the list as you see fit:
God did not create the universe
Our universe was formed via the expansion of a singularity and subsequent formation of structures by hydrogen atoms through gravitational attraction. A magical deity adds nothing to the known explanation.
God did not create the solar system or the Earth
Our sun was formed by the particle clouds left behind from previous stars, and our planet (as well as every other planet in the solar system) formed from an accretion disk surrounding our sun.
God did not create life on Earth
Life on Earth was formed through a chemical evolutionary process known as 'abiogenesis' (not to be confused with modern evolutionary science, dealing with the propagation of alleles through a population).
God did not create homo sapiens
Homo sapiens evolved along the primate branch of the genetic tree. We are simply the 'latest model' of great apes.
God did not give us 'souls' or 'free will'
Human beings are conscious and self-aware via their brains. An extra, magical source for our intelligence adds nothing to the known explanation.
God has yet to answer a prayer
Under controlled conditions, when a request is made via prayer for something unambiguous, nothing ever happens.
God did not provide us with accurate insight into the mechanics the universe he supposedly was somehow involved in erecting
None of the mythological texts supposedly divined into existence by God reflect reality.
God did not talk to you last night
You can kid yourself and your choir all you like. We both know it didn't happen.
God did not send his Holy Spirit through you
God did not invent morality
Morality was a trait favored by natural selection, as it encourages population growth & stability.
What the Hell did God do that is apparently so obvious to you? All of the things traditionally attributed to God are mis-attributions; it's just outright wrong to say that magic was somehow necessary to make the universe, Earth, people, etc. We also both know that you're being dishonest when you claim that a prayer was magically answered or that God manifested for you.
So: where does God come into it?
"Natasha has just come up to the window from the courtyard and opened it wider so that the air may enter more freely into my room. I can see the bright green strip of grass beneath the wall, and the clear blue sky above the wall, and sunlight everywhere. Life is beautiful. Let the future generations cleanse it of all evil, oppression and violence, and enjoy it to the full."
