If You Were God of the Universe, Would You Only Have TWO Hands?

In Quran 5:64 it is written "And the Jews say, "The hand of Allah is chained. Chained are their hands, and cursed are they for what they say. Rather, both His hands are extended..."  Why does the mighty god of the universe have only two hands, and not 70,000?  Why does the mighty god of the universe need any hands at all?
