I'm using "educated" as a way of saying well informe people, mainly in history matter. When you know the history of humanity, not just the western history, you will notice a lot of patterns among religions, which proves it's human-made.
But if you forgot for one moment the concept of the God religions pose, which is very annoying to me, you would notice that our existence needs a "raison d'etre", a cause, an inception, or at least a convincing explanation if you like so, something that science can't give because of its evident limitations. And by doing so, it's obvious that we, as educated people, would cast religions out in such search.
