Paul, who was described as the 6th most influential person in the history of the world according to the book "The 100: a Ranking of the 100 Most Influential People in History" stated he saw Christ in his own words and thus was an eyewitness. He also states he was the last to see Jesus.
1 Corinthians 15: 3-8
For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures, and that He was seen by Cephas, then by the twelve. After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep. After that He was seen by James, then by all the apostles.
