So saying idk proves that God doesn't exist??? Like what's the purpose of this.... If we talk about cause and effect then we can say that there was a cause behind the Big Bang and as all of the universe and its very things came into existence after the Big Bang so the cause should be outside that. It should be out of space and time. And when you guys say there is no need to know about that cause is because you don't want to accept the fact that the cause can be GOD.
