Religion is nothing more than a useless and sometimes dangerous, evolutionary accident. Religious behavior may be a misfiring, an unfortunate byproduct of an underlying psychological propensity which in other circumstances is, or once was, useful.

If you have a faith, it is statistically overwhelmingly likely that it is the same faith as your parents and grandparents had. No doubt soaring cathedrals, stirring music, moving stories and parables, help a bit. But by far the most important variable determining your religion is the accident of birth. The convictions that you so passionately believe would have been a completely different, and largely contradictory, set of convictions, if only you had happened to be born in a different place.

God is the answer to all of those "How must it have come to be" questions.

If you don't know anything about computers, just remember that they are machines that do exactly what you tell them but often surprise you in the result.
