The original question: “Where is the list of the 500 people that is claimed to have witnessed the resurrection of Jesus?” is answered by the Apostle Paul that the Corinthians can still meet some of the eye witnesses of Jesus’ resurrection.
“For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried,that he was raised on the third day according to the Scriptures, and that he appeared to Cephas, and then to the Twelve. After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, 8 and last of all he appeared to me also, as to one abnormally born” (I Cor. 15:3–7).
Luke records that the Lord appeared to them over a period of 40 days and spoke about the kingdom of God (Acts 1:3). It is reasonable to think that that the appearance of Jesus to the 500 happened within those 40 days when the Apostles were among that crowd. It was not Luke’s intention to list all the appearances of Jesus but ones that relates to the Apostles as the text continues with theses words, “On one occasion, while he was eating with the, he gave them this command, “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about…” (Acts 1:4).
The Apostle Paul even declares that if the Corinthians believers or skeptics don’t believe his testimony of Jesus’ resurrection that they can go to Jerusalem and meet some of the eyewitnesses of Jesus’ resurrection themselves. If there were any skeptics of Jesus’ life and resurrection, I would imagine that they would have went either to disapprove or confirm the life and resurrection of Jesus. Thus the resurrection of Jesus was well established by the testimony of the Apostles, the women, and 500 other people.
Note carefully in Acts 1:23–26 that two other men, Joseph called Barsabbas and Mathias were also witnesses of Jesus’ life:
“Therefore it is necessary to choose one of the men who have been with us the whole time the Lord Jesus was living among us, 22 beginning from John’s baptism to the time when Jesus was taken up from us. For one of these must become a witness with us of his resurrection.” Josephus and Mathias were equally qualified to be witnesses of Jesus’ life from John’s baptism until Jesus was taken up from us. Thus there were other witnesses which is not recorded in the Gospels.
It has been argued that why aren’t there other records of the life of Jesus. Luke records in 1:1–4 these words: “Many have undertaken to draw up an account of the things that have been fulfilled among us, 2 just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. 3 With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, 4 so that you may know the certainty of the things you have been taught.” Those records have been lost.” Those historical documents are lost or not preserved.
SUMMARY: The resurrection of Jesus is true and not a fable.
