I prefer the term "conjecture based on deductive reasoning." It is reasonable to presume that something is theoretically possible unless we have specific evidence that it is impossible. For example, even though it is impossible today, most people would agree that it's theoretically possible to create self sustaining colonies in other solar systems. "Faith" usually implies less, or even no, basis in reason. If you still feel "faith" is the more appropriate term, please explain your reasoning.
