God vs Rocks

Can God create a boulder so big that he cannot lift it? This enigma is supposed to prove that God is not all powerful and therefore not God.

This reminds us of those who tried to trap Jesus by asking if taxes should be paid to Caesar.

The answer was render unto Caesar what belongs to Caesar and unto God what is God's.

God cannot make a triangle with four sides or a square circle because these are contradictions of logic and God is not illogical but logic itself. 

Anyone with sand and cement can create a boulder that he himself cannot lift. That is not a test of divinity but might be a proof of stupidity if done just to entertain fools.

God is not into lifting boulders to entertain small minds. But rather offering wisdom to small minds so they can get the rocks out of their heads.
