The two most important questions in science are “What can I know?” and “How can I know it?”

Science and religion in fact part ways over the first question, what each can know. Religion, and to some extent philosophy, believes it can know, or at least address, the question, “Why?”

For most religions the answer to this question ultimately comes down to the way God ordered it. Religion is inherently conservative, even one proposing a new God only creates a new order.

The question “why” is too deep for science. Science instead believes it can only learn “how” something occurs.
