Nature speaks in and of itself, in every thing you see. Al-Quran speaks of "everything being a sign, an Aayah". "One and one is two" is just as much an Aayah as "None & None is Noo." If you think that Man had to come around to _invent_ the truth, then please go on thinking so. *smile*

It won't change the fact. One & one will _remain_ Two. And what we haven't yet learned (iota) times what we still need to learn (iota) will yet remain equal to -1. (Yes, I speak of IOTA * IOTA = -1)

Discovered.

It's a language in which the universe is written in. We may not have discovered it in it's original form and thus we have multiple representations of it (as kapagama mentioned his with real vs rational vs natural example).

It couldn't have been invented. It's too methodical to have been man created. It's almost like saying we, as humans, taught ourselves how to think when in fact, we had to know how to think in order to teach thought.

neither. mathematics does not exist.
