Question

If God doesnt exist, who or what do you think is capable of playing such a sick joke on human kind?
There are too many possibilities, although, I find solace and comfort in confiding in my God. Nevertheless, My imagination is afraid of the things I might come up with. What else could willfully do this to us, and why?

Answer

the fact that we humans are imperfect, made us to create an image in our mind in which we can seek perfection.
