How genius a person is is measured by his IQ. Are you suggesting that there has never been a man or a woman in history who has a higher IQ than Einstein?
What I meant was nobody would have discovered what Einstein discovered. Also, it is not only IQ what makes a great genius like Einstein, but his or her imagination. Not all people with high IQ have great imagination. That is why we have only one Newton, one Einstein etc. They were very unique people. You said: Moses’ miracles are not verifiable today. (In fact, to a certain extent, they are even imitable.)You accept it on the basis of faith and that is subjective. Not so with the Quranic miracle. It is verifiable and therefore more objective.
