A Rabbi says:
"Of the 15,000 religions in human history, only Judaism bases its belief on national revelation -- I.e. God speaking to the entire nation. If God is going to start a religion, it makes sense He'll tell everyone, not just one person.
Judaism, unique among all of the world's major religions, does not rely on "claims of miracles" as the basis for its religion. In fact, the Bible says that God sometimes grants the power of "miracles" to charlatans, in order to test Jewish loyalty to the Torah (Deut. 13:4). . . .
. . . Judaism is not miracles. It is the personal eyewitness experience of every man, woman and child, standing at Mount Sinai 3,300 years ago."
Wait a minute . . . Didn't all those eyewitnesses die in the wilderness without ever writing a word about it or proving it to other people? Even if Moses did write about it (he didn't) that's still only one witness (not enough) and he died in the wilderness also.
Well . . . "poof", no eyewitnesses.
