The theories (and concepts) I know about science

During my secondary school, I studied the science subjects: physics, chemistry, and biology.

The main theory I know about the physics is: Energy cannot be created or destroyed, it can only be transformed. Then I asked, where does energy come from? Is it existed in the beginning?

Then, about the chemistry, which studies about the matter. From this subject, I know an atom consists of proton, neutron, and electron. We can determine the element based on the number of protons. Then I asked, what determines the number of protons? There should be some attractive force, but where does this attractive force come from?

Then, about biology, my biology is the poorest among the the three subjects. The main theory I know about biology is the DNA. Even the plants and animals have a very distinctive biological system, both of their DNAs consist of same bases: A, C, G, T. And my text book written, this indicates that both plants and animals have a same creator.

Even these are the science subjects, these subjects helped me grow more in spirituality.
