Peter, Paul and the other Apostles didn’t give written accounts of their personal, contemporaneous relationships with Jesus? Really?
The gospels were not written until decades after the events they depict were supposed to have happened, so they aren't contemporaneous. They are also anonymous.
"...The word is primarily used to refer to the four canonical texts: the Gospel of Matthew, Gospel of Mark, Gospel of Luke and Gospel of John, probably written between AD 65 and 80. [1][2] They appear to have been originally untitled; they were quoted anonymously in the first half of the second century (i.e. 100 - 150) but the names by which they are currently known appear suddenly around the year 180.[3]"
