"What did Jesus look like?"

We know from the "Letters of Abgar V" and “The Mandylion of Edessa” that Jesus looked a Syrian from the royal family of Nasara. He looked like Assad.

"Why are there no third-party accounts of his supposed great works and miracles?"

There are other accounts, but they are Armenian, Persian/Parthian historians that were not under the restrictions of the Roman Empire and Titus Flavius Caesar who only allowed a few authors of publishing houses, Josephus and Plutarch to name two.

"Why didn't any of his followers write anything about Jesus? They had lots of opportunity and some were learned men."

Because Josephus was the only royal/historian allowed to write anything about Judea at the time.

"Why does Paul contradict Jesus on several key points like obeying Moses' law?"

The New Testament contradicts the Dead Sea Scrolls because it is the Roman version of Christianity versus the Jewish Messianic militant 4th Sect. Paul is listed indirectly in the family tree of Herod. If you look at Drusilla Herod, you will find that she was married to Azizus king of Emesa(Jesus) but Drusilla left him for Antonius Marcus Felix. His brother's name was Pallas(Paul). So you see, Paul was the rival of Jesus.

"Why do modern Christians follow the teachings of Paul instead of Jesus?"

Because Titus Caesar became king of Judea after the fall of Jerusalem and Azizus(Jesus/Judas) of Gamala(Gamaliel) became a prisoner. Josephus became the Caiaphus and governor of all Judea on behalf of Titus.

"If original sin comes from Adam and Adam didn't exist, then what original sin was Jesus dying for? And follow-up, why would a perfect being screw up so badly in this regard and need to fix it in such a convoluted way?"

You have to remember that Adam and Eve represent the royal traditions of the Hyksos kings and queens of Babylon, Lower Egypt, Judea and finally that of Rome. The Babylonian Trinity is the Hyksos Trinity. This is why the Adam and Eve story exists in Mesopotamia, Egypt, Israel and in the Roman Christian west.
