So this is your evidence that Matthew was indeed the real author? That the order of the listed names proves it's true? Sounds like something out of the morning sermon at the First Self-Righteous Church of Got No Clue.

What would they have known about anything? Could they read or write? Probably had not one minute of school and yet they were a discerning group?
