The evidence of life and creation tells you there is intelligence.
And the evidence of life and evolution tells you there is no intelligence.
You can not prove creation, because you have no tool, logic, method other than belief. You are talking about vastness of things, universe, humans, and everything else. Fair enough. And your logic goes like that: "If everything are so much and complex, so they can not emerge by themselves, a creator must be behind of everything." Ask yourself "why"? Why do you think that complexity can occur only through a creator? You have raised the human examples (bread, machines, etc.), yet there is no single human being or single time or place behind all these human inventions (factual or fictional); they are the results of accumulation and combination of many individuals accross the planet and throughout millennia.
Anyway, I will not go through the examples from technology, such as how any complicated device (a car, a computer, a scanner, etc.) has evolved throughout centuries. I will just ask you to start to think about two concepts for a beginning: Heredity (history of everything) and the immense time span was (comparing to the life span of an individual, a country, a religion, a species) required to reach actual situation of reality which present itself upon us. Plus don't underestimate the possibilities which may and do arise from the co-existence of things (physical) their environment. It's like thinking of internet environment as a combination of many individual ideas, projects, contributions, demands, as well as technology behind it. No single person could create the internet, no matter how intelligent they were.
I think I can not give you anything more than this. Because idea of evolution is not trying to sell you a brand new belief: The whole idea is to test your belief against reality. Try better devices to see the reality. No matter how better your eyesight is, you cannot see microorganism or distant galaxies without the help of microscopes or telescopes respectively. No matter how intelligent you or somebody else is, you can not create complex mechanisms (internet, cosmos, life) single handedly let alone suddenly.
