Acts 2:32 sets forth the claim of the apostles and disciples — they had seen Jesus Christ (Y’shua ha’mushiach — pardon my poor transliteration of the Hebrew) risen from the dead in a physical bodily form. This witness is a major key of Christianity.
Many, perhaps most of these men and women would go to their deaths concerning this witness. Thus, most of the usual tales of why the Bible is not accurate fall flat. People don’t go to their deaths to defend something they know is not true.
Those listening to Peter preaching at Pentecost (Feast of Weeks / Shavuot) could go and talk to the apostles/disciples and see if a consistent story was told. They could listen to the prophecies that were fullfilled from Psalms 16 and 110, and Joel 2. Three thousand were converted that day. The story circulated by the authorities that the disciples stole the body of Jesus could not stand up to the miraculous signs and wonders of the day, and the witness of those that had seen the risen Jesus Christ, of which there were at least five hundred.
What could make despondent followers of a dead teacher react with fervor? The truth that the teacher was alive, and was ruling from heaven. After the death of Jesus the disciples and apostles hid. They did not want to be killed as well. The resurrection of Jesus Christ and the empowering of the Holy Spirit overcame their fears, and the taught the truth of the risen Messiah, Jesus Christ.
