回复：上帝能造一块他自己搬不动的石头吗？

In logic this is a paradox caused by self referencing. Another example is that a barber in a village who cuts the hair for everyone in the village who doesn't cut his/her own hair. The question is who cuts the barber's hair. The answer, which has to avoid self referencing, is that God is selfless, and never creates anything for himself to consume.
