The Jews (I’m not addressing the “mixed multitudes” of the times) did not reject Moses, he was their rebbe and leader. They feared leaving the relative spirituality of living in the desert, surrounded by miraculous godly clouds, fed from manna from heaven, and involving themselves with nothing but studying G-d’s Torah in all its depth. Not a bad life. Then....they were told to go be farmers... big challenges ensued (not to mention that Moses would not enter the Holy Land with them...)
So that’s the Jewish perspective. They (and we) certainly don’t reject the Messiah ;-) But you know what I mean.
To my original comment, science cannot “prove” the age of the earth. We Jews know that Torah is objective and true, and hence know the age of the world. Interestingly, no scientist can prove that Torah at Sinai did not happen (G-d forbid) because one cannot prove something from a negative inference.
You are being charitable, but Scripture testifies that, like us, they were overall rebellious and drew back in faith in the tests they faced, which i have shown i can do as well.
Thus the testimony of Moses was, “Ye have been rebellious against the Lord from the day that I knew you. “ (Deuteronomy 9:24) See also Ps. 78, 106.
And the overall rejection of the Messiah was that of Jesus Christ.
