Where are you getting this information? How do you know nobody challenged Jesus? You didn't answer that question.<quoted text>
1)It matters because,The Pharisees,Saducees ,the lawyers and the Scribes were the supposed experts in interpreting Scriptures
When Jesus made his claims,if those claims were inaccurate,
they would have been able to cite the Scriptures in order to demonstrate that Jesus was lying.
But ,they did not.
Also, the analogy of psychics is related. You are claiming that people who lived before JC predicted JC. That is what psychics do. The same tricks used by Christians to make it seem like JC was foretold are the same tricks used by Sally Brown and other psychics to fool people into thinking she has magic powers.
It is directly analogous.
