Who created Hume?

"We are still obliged to mount higher, in order to find the cause of this cause, which you had assigned as satisfactory and conclusive.... How therefore shall we satisfy ourselves concerning the cause of that Being, whom you suppose the Author of nature, or, according to your system of anthropomorphism, the ideal world, into which you trace the material? Have we not the same reason to trace that ideal world into another ideal world, or new intelligent principle? But if we stop, and go no farther; why go so far? Why not stop at the material world? How can we satisfy ourselves without going on in infinitum? And after all, what satisfaction is there in that infinite progression?"
-Hume, Dialogues Concerning Natural Religion, Pt. IV. 1779.

(The above is a statment regarding the First Cause Argument: That everything has a first cause. This is sometimes used as a reason for believing in God, but those supporters never ask "Who created God?" thereby invalidating their own argument.)
