I’m personally not going to debate it (I’m an atheist but I don’t proselytize) but given the sensitivity of the topic it seemed more apropos for her than General Questions.
I wondered this even when I was religious: why would an omnipotent, omnisicent Being who was and is and e’er shall be complete unto Himself feel the need to create humans (or anything else, for that matter)? Is it for the worship? The companionship? An experiment?
I’m not mocking the views of anybody, but I am curious what they are.
