The question is, Where did the complexity come from that made the little, simple equation possible?
Therefore, your argumentation for the proof of God's existence is...?
It can't possibly boil down to "complexity = God" right? That seems like a very strong non-sequitur.
While you're considering this, allow me to present a thought experiment. Given the typical approach to the Abrahamic god, it is simple to create a utilitarian environment in which the highest number of people are given the best possible afterlife.
How do we do this? Simple! Maximize reproduction
and infant mortality! We use one sinner to "carry our sins" and send as many people to heaven as possible. If they don't have time to turn against theism, then they won't have time to reduce their afterlife to that of hell!
That's what a truly moral person would do, were they to honestly believe in their Abrahamic religion.
Your thinking in this first part isn't complex enough. Exhaust comes from a car. Does this mean that the exhaust is the car?
Whatever God actually is, there is no way for people with their simple intelligence to know. People can't even figure out the complexity that comes from God.
If the operation of the universe, the goals that God has, the thing that people are, the way God has placed Himself into the universe with His strength, and a whole host of other things, were the simple way you picture the Abrahamic religion, why even make the universe? Why not make people to be in Heaven without a universe at all?
Since God made things way more complex than the simplicity you are talking about, time for you to calculate why God would do this. Perhaps you can become a bit more realistic in the things you say.
As God says through the prophet Isaiah, Isaiah 55:9:
As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.
As God says through the psalmist, King David, Psalm 103:11:
For as high as the heavens are above the earth, so great is his love for those who fear him;
You really need to see how great the complexity around us really is!
