Butterflies61 - once again a Christian shows appalling ignorance of the origins of the New Testament. To say that Matthew, Mark and John were "with Jesus" is nonsense. They are names given quite arbitrarily to four of the three totally anonymous gospels late in the 2nd Century.
Any assumption by you that the evangelists "Matthew" and "John" were the disciples of that name indicates that you don't know the chronology of the matter.
"Matthew" was written about AD85-90 when any contemporary of Jesus would have been in his dotage (more probably dead). Quite apart from the fact that there is no evidence to link the two, why would an eye-witness wait until after three people that no knowledgeable person claims were eye-witnesses (Paul, "Mark" and "Luke") had given their stories? And why would he copy whole chunks verbatim from the earlier "Mark"?
The same in spades goes for the apostle John and the gospel "John", which was written somewhere between AD90 and AD120. In that case we would have to assume that a horny-handed Galileean fisherman, whose native tongue was Aramaic, suddenly, nearly a century later, wrote in elegant Greek a gospel full of mysticism and Hellenism.
We don't know who wrote the gospels; I wish we did.
I suggest you read a few books about the structure of the NT and a few more about evolution - two subjects about which you plainly know little but are nevertheless happy to pontificate on.
