Reason and experience sprinkled with divine revelation.The logic doesn't follow ....Everyone has to. So why not god if we're made in his image?Why?Our god must have a mama-god and a papa-god.
Being made in His image doesn't necessarily mean He was made the same way we were ... you give humans WAY too much credit.
I understand. If you have a made up God, there is no reason why you can't just make up a bunch of stuff to describe him.
You really have no excuse.
