I believe that Elder Scrolls are the universe responding to the happenings of Mundus.

Think of it:


 * They are uncountable because something can either happen or not happen, thus rendering the Scroll existing or unexisting. However, because something happening or not happening is decided by all living things, Scrolls oscillate in and out of existence.
 * For all his power, Vyrthur wasn't a god. Hence, he couldn't have actually written the Elder Scroll. However, when he realized that the Sun could be blocked by tainting Auriel's Bow, the Aurbis responded by creating two Scrolls that detailed how it could be done, due to such an event having potentially massive influence on the world. Because of unlinear nature of time, the content of Scrolls kept changing, ever tracking the Bow (because we know that the Bow wasn't always in the Chantry).
 * They deal with obscure subjects, such as CHIM. I highly doubt that any Aedra were capable of achieving CHIM, and by extension, didn't know anything about it.
 * They are indestructable, because as long as there is a chance of something happening (or something having happened), there must be a Scroll to speak of it.
