It was the Jews who predicted the coming of the Messiah. They knew what the Messiah was supposed to accomplish. They knew the Messiah had to come from the linage of a specific Biblical family. Anyone else would be an impostor, not the real thing.
To be the Messiah, one could not just claim the god had told him this. Someone else needed to hear it, otherwise anyone could make this claim.
No one else heard the god tell Jesus he was the Messiah. That should make everyone skeptical.
Then, there were tasks the real Messiah was supposed to accomplish. The self-claimed Messiah, Jesus, did not accomplish these tasks, raising more doubt.
In addition, the messiah was to have been a descendant of King David. This is a clear requirement that is either met, or, not met. The Jesus does not make the grade.
Nonbelievers raise similar issues with the claim the Biblical character, Jesus, was the Messiah. They ask believers how, exactly, will we identify the real “returned one” if there are several who make the same claim? Jews anticipated this problem by being very specific about how to identify the “one”.
Jews also fault the “Jesus story” in its portrayal of a “virgin birth”. Their view is virgin birth was not a requirement. It’s in the story by mistake.
Jews have their own strange myths nonbelievers do not accept. But their criticisms of Christian myths are logical.
The Jews have legitimate skepticism.
