Then why don’t you let us know. How do you know that you are not in some ‘Matrix’ existance where your reality is not computer generated, and no one but yourself exists in your reality?

Sigh. I don’t. How do you know that we’re not powered by microscopic gnomes turning little cranks rather than cellular respiration? How do you know the sun will rise tomorrow? This quickly becomes an ontological exercise.
Prior events tend to be good predictors of future events. Natural selection, mutation, and speciation have all been observed. The age of the earth can be ascertained by uranium-lead dating of meteorites or of galena deposits. Is it possible that God places his invisible hand somewhere in the system making it appear that the earth is older than it is? Yes. Is it possible that we’re all in the Matrix, and that the earth is really even older, but the machines make us think it’s 2006? Yeah, sure. But there’s little to no unique evidence in favor of either of those hypotheses, and a more parsimonious explanation is that things really are the way they seem.
Should we start teaching the Matrix Theory? It is, after all, a possibility. But it should become instantly obvious why we don’t teach all possible hypotheses. Why can’t we be content to teach the hypotheses that the data support?
