Machine-like nature of the universe. All around us, in nature and the universe we see machine-like operations. These operations are extremely complex inside life and the cells. Machines have makers.

Animals use simple machines. Some primates (apes, chimps, monkeys) use rocks and sticks to work their food. The leverage they provide with the rocks and sticks is machine use.
People use simple machines. People make and use complex machines. All machines that people and animals make and use come from examples of machine operations in the universe.
The progression is that, as the machines that people make and use are far more advanced than the ones that animals make and use, so are the machines that exist in nature far more advanced than the ones that people make and use. The advanced machines of the universe have an advanced Maker - God. Machines have makers.
So you consider life and cells to be machines. And you consider that these machines can make other machines. What made the machine you call God?
Using this logic, everything is made by something else, and it would go on forever. Where does it stop? Are we to accept that God is exempt from the logic you use in this argument? You may respond with something along the lines of "God is the beginning of this progression, the thing that created the universe, and he existed for all time." Well, if there IS in fact an beginning to the progression of machines creating machines creating machines, why can't it be the Universe itself? What if it does not need an intelligent creator and it has existed forever - since time is only extant in the universe it effectively could have existed forever even considering the Big Bang theory. What's even better, is that we know the universe exists and it can be proven by conventional science (so far as proving that anything effectively exists could do). Making things with a specific design in mind is more on the human/advanced animal level, but the universe can certainly create, through the extant and provable laws of physics and semi-random processes. Keep in mind that in the current scientific view, the world is at least 4 billion years old, and the universe much older yet. Just considering the fact that matter and the laws of physics exist, you would expect SOMETHING to happen in all that time. For all we know, there could be a set of "machines" somewhere else in the universe that is far more advanced than what we call "life".
If I were to have a God to account for the universe, it would be the universe itself - matter, energy, and the laws of physics and other fundamental scientific/mathematical laws (maybe even some we haven't discovered yet) - not a sun god, not a lightning god, not a judgemental god that focuses on abstract ideals like good and evil, or even a loving god that watches over each and every one of "His children" and listens to their prayers (of course choosing which ones to answer according to His will alone).
