Here is the first link dealing with the Gospels:

Composition
Like the rest of the
New Testament, the four gospels were written in Greek.
[30] The Gospel of Mark probably dates from c. AD 66–70,
[5] Matthew and Luke around AD 85–90,
[6] and John AD 90–110.
[7] Despite the traditional ascriptions, all four are anonymous and most scholars agree that none were written by eyewitnesses.
[8] A few conservative scholars defend the traditional ascriptions or attributions, but for a variety of reasons the majority of scholars have abandoned this view or hold it only tenuously.
[31]
In the immediate aftermath of Jesus's death, his followers apparently expected him to return at any moment, likely within their own lifetimes, and consequently there was little motivation to write anything down for future generations. However, as eyewitnesses began to die, and as the missionary needs of the church grew, there was an increasing demand and need for written versions of the founder's life and teachings.
[32] The stages of this process can be summarised as follows:
[33]
- Oral traditions – stories and sayings passed on largely as separate self-contained units, not in any order;
- Written collections of miracle stories, parables, sayings, etc., with oral tradition continuing alongside these;
- Written proto-gospels preceding and serving as sources for the gospels – the dedicatory preface of Luke, for example, testifies to the existence of previous accounts of the life of Jesus.[34]
- Gospels formed by combining proto-gospels, written collections and still-current oral tradition.
