All of the "revelations" above are of one person attempting to convince others of their divinity. No one can really know if its truth. As you've stated, none of those "revelations" have stood the test of time. As soon as the yoke is lifted from their backs, the belief dies. But Judaism's national revelation is unique in the world. The text of the Torah states D e u t 5:4 Face to face, the Lord spoke with you at the mountain out of the midst of the fire: No people would ever accept a story that they themselves witnessed a miraculous event unless they had really done so. If G-d wants to start a religion, then the best way is by presenting Himself to the entire nation, not just through a text that somebody wrote. If Moses made the whole thing up, then his story would've died with him.
Maimonides states (Foundations of Torah, ch. 8):The Jews did not believe in Moses, our teacher, because of the miracles he performed. Whenever anyone's belief is based on seeing miracles, he has lingering doubts, because it is possible the miracles were performed through magic or sorcery. All of the miracles performed by Moses in the desert were because they were necessary, and not as proof of his prophecy. What then was the basis of [Jewish] belief? The Revelation at Mount Sinai, which we saw with our own eyes and heard with our own ears, not dependent on the testimony of others... as the Torah says, "Face to face, God spoke with you..." The Torah also states: "God did not make this covenant with our fathers, but with us – who are all here alive today."
Judaism is not miracles. It is the personal eyewitness experience of every man, woman and child, standing at Mount Sinai 3,300 years ago.
