Take Judaism for instance - what we call Judaism today is Rabbinical Judaism, founded in 70 AD by Rabbi Yohannan Bin Zakkai out of Pharisee-ism - because ALL the other 2nd temple Jewish sects (with the exception of the Jesus-movement Jews (later called Christians)) had died out with the destruction of the temple. So it is younger thant the Church, which was founded in 33 AD.
You just keep repeating that lie hoping that it will stick.
"Rabbinic Judaism" was no more founded by Yochanan Ben Zakkai than Catholicism/Orthodoxy was founded by Constantine.
I know you're not a big fan of the Hebrew Bible ("Old Testament"), but if you were to read Deuteronomy 28:15-69 you would see that from the beginning the Torah predicted that the Jews, if they strayed from the Torah (not "rejected the Messiah") would be exiled from their land and thus without a Temple cult for a very long time. Deuteronomy thus refutes the ignorant idea that Judaism was set to expire when the Temple was destroyed. I can see why you want to ignore this, but it's still deceitful and probably offered in bad faith as well.
Of course, you probably believe Deuteronomy was forged by Norman Mailer and retrojected into the distant past, but that's your problem.
Dishonesty is not a good argument.
