no. even critical scholars can trace most texts to the mid-to late 1st century, within the time of the apostles. the gospel of mark was likely one of the first books written in the new testament, probably in a.d. 55-59. some scholars want to put it post 70 ad due to the prophecy of the destruction of the second temple, but it is generally agreed mark was the first one composed. the last one being the gospel of john in 90-95 ad while he was still alive. all of this was within a 60 year time period post crucifixion. i think that it is fair to bring up the question of authorship. but we attribute to plato and aristotle their works from copies 800 years after their original composition. i just think an unfair level of skepticism is raised against the gospels because of their metaphysical implication.
