3) the idea of atheism at birth is debatable but I kind of agree with it. But in my case I came to god because of science. I wondered why water- a liquid made exclusively of hydrogen and oxygen is the way it is; why only molecules of H2 and O2 were drinkable and unique among all substances. Why water hosted the first living things on earth. An accident that hydrogen and oxygen were meant to join and host microorganisms? I'd differ

I think you are looking at this wrong.

Lets suppose water is necessary to life (it probably is). Why does that mean it's designed by a god? Every other chemical in the universe is unique among the chemicals in one way or another. Many of them are necessary to life on earth as it now exists either directly or because they are involved in creating our atmosphere or creating solar energy. Life is formed from and uses the materials at hand. It would be odd if it used materials not available.

Saying that the materials were specially created to sustain life is like saying that trees were designed to become lumber and food for deer, or that they were designed to fuel forest fires. People, deer, and fire, all use them but they weren't made for that purpose. But deer and people took advantage of them.

Or look at it this way. My home is a perfect environment for carpenter ants. It has water, habitable materials, and food. Ants like it. But I sure didn't design it for ants. But by your logic the ants could argue it was designed for them by god.

4) complex organs in organisms. A leopard's eye, a cheetahs legs, the human brain computing thousands of stimuli and the functionality of organs. Evolution? Yes. But such intelligence in their designs.

What you are doing here is answering the question how does evolution occur with god. It's a null answer. It tells you nothing more about how life evolved than "just because." And it supposes something much more complex than the question, i.e. a god complex and powerful enough to direct evolution. All of which is silly because there is an adequate much simpler answer: natural selection.

More importantly, I don't think that these are really your reasons for believing in god. I think they're are explanations you make to others to explain your belief. These arguments came after belief not before.
