Are some of you suggesting that just because I don't understand all the science, it doesn't mean that it isn't true?
It is about understanding scientific method, (or at least what it is). If that can be understood, it will provide a basis for understanding the reasoning of why something is considered fact. And yes, in science a theory is also factual. (Not absolute truth...It is a big no-no to even say the word "truth" in scientific circles).
