What a rich combination of condescension and sophistry! You write as if having confidence on some subjects is the same as thinking you know the truth about them all. And you guess that those with the temerity to express the belief that, e.g., evolution is true (even when applied to H. sapiens!) are arrogant youths who don't yet understand that 300 years ago people believed lots of things that turned out to be wrong. No "real" scientist would talk that way, but don't worry, "you will mature." Well. My confidence is born of study and reflection, not youthful arrogance. In fact, I am a middle-aged scientist (a real one!). I weight my degree of confidence according to my understanding of the evidence, reserving judgment when the evidence is insufficient to justify a strong conclusion. I'd guess you strive to do the same. Indeed, I'd bet you're confident that evolution is right, and you'd probably cut creationists even less slack than I would—which makes your "knowing the truth is not possible" pablum utterly disingenuous.
