These are numerical coincidences that cannot be derived. The fact that atoms exist at all, as opposed to a universe that consisted entirely of elementary particles is contingent on the force laws by which the elementary particle interact. That's a word you think you know how to use. I do know how to use it. The fact that we call them constants is not arbitrary.
Facts are never arbitrary.

Life is hardly as fragile as these creationist like to believe. This sort of assumption is based on what people are calling the principle of univesalism .
