Nothing is made from nothing. - René Descartes

La existencia de Dios debe tenerse en mi espíritu por tan cierta como las verdades de las matemáticas que no contemplan otra cosa que números y figuras.

But this could not be the case with-the idea of a nature more perfect than myself; for to receive it from nothing was a thing manifestly impossible; and, because it is not less repugnant that the more perfect should be an effect of, and dependence on the less perfect, than that something should proceed from nothing, it was equally impossible that I could hold it from myself:

I am thing that thinks: that is, a things that doubts,affirms, denies, understands a few things, is ignorant of many things, is willing, is unwilling, and also which imagines and has sensory perceptions.
