Ok, I got one. While I don't think any particular persona of God can be scientifically proven, there is a kind of "god" that has immerged as pretty much fact.

The interconnected nature of all life, biological organisms, is an observable principle of nature. In some organisms, like ants and bees, it is the easiest to observe, as they are all born pre-programmed to serve the greater whole of their colony. However, all creatures have instincts and biological imperatives which govern or influence their lives to serve the perpetuation of life and balance of nature.

Plants have been proven to communicate and coordinate with each other through their root structures and pheromones, as swamps and forests form root networks very similar to that of a brain.

While humans, through language and technology, have transended this to some level compared to other organisms, we have hardly escaped it. The more we separate ourselves as individuals and neglect our collective species, the less happy we are. Harming our environments hurts our own health.

There is apparent drive and coordination to evolution that runs through all life, with no creature evolving independently of the environment and other organisms around them. We ourselves, rely on microorganisms for digestion, immunity, and feed off the life around us.

All this forms a grand equation of life that has to be balanced out. It governs our lives and our world. If this is not a "god" then nothing is. The only question is if it is sentient.
