So God can't create something which works by itself?
An automatic gearbox doesn't cancel the inventor does it?

What's the point of positing God if things can work by themselves anyway? Learn to use some Occam's razor when you get the chance.

Life and automatic gearbox are two different things.

Do you have any evidence of things outside of God's creation, that just appear by organizing themselves into functionality and working?

No, but you want to use God's creation as an example of that?

So apart from nature, including the functionality of the elements and chemicals, you don't have any evidence that things work by themselves.

Things don't work by, or create themselves. That is a fact, not a theory.
