You have asked some interesting questions. You are Knock knock? I have not heard of you. I hope your intentions are good and not for confusion. If you really want answers, have you sought the face of God for them? Are you a born again child of God? You need to understand that no man can see what the scriptures mean unless he is born of God first. So when you ask questions like this under false pretenses, you will bring upon yourself 'issues' from God, just because you are doing so in 'fun' to make fun of his children. If you really are curious enough to know the answers - study it out yourself. Then if you still need help, come back here. By the way, that stone is not the stone at Mecca.
