And Jesus said?

Maybe 30 years afterwards.
Jesus words were passed on the same way other human deeds and words are passed on. Oral tradition, writing. Preservation of documents.

Passing it on requires people, and at some point it asks for your trust in people.

And this is a fact, that His exact words were passed on in the ways you describe or are you guessing?

I am not sure what you are looking for.
Think about how family traditions are passed down. Frequently, siblings and friends will treasure events and favorite sayings of deceased family members. These will be repeated in an oral tradition. Some write them down. Now we have photographs also.
Larger historical families will be documented more widely than just our families. This is all part of human communication.

In Christ, we have Inspired revelation. Christ is the Son of God and Son of Man. Through Inspiration we have saving truth from God, passed on through human communication. The apostles treasured the words and deeds of Christ. They would have spoken about him to others (see the Acts). Even as Christ walked the earth, the Word spread. This is then committed to writing to preserve it.

This is all about people. The Church is made up of people who communicate the Gospel.

When were these accounts of what Jesus said written?

Much has been written about this topic, here on the forums, and elsewhere. I found the following books helpful:

In view of this uncertainty, two lines of approach may be followed. One is the ancient tradition of the Church about when the Gospels were written. This tradition is not entirely consistent. The earliest tradition indicates that Mark was written after Peter’s death, which may be dated in A.D. 64. A later tradition suggests that Mark wrote while Peter was still alive. Probably the date after Peter’s death should be preferred (A.D. 65–70). Then, if Mark was a written source for Matthew and Luke, these two Gospels must be dated some years after this date of Mark.

Another method of dating the Synoptic Gospels starts from the book of Acts. Acts ends with Paul spending two years in prison at Rome (28:30), ca A.D. 61–63. If Luke wrote Acts while Paul was still in prison at Rome (one view is that Luke wrote Luke-Acts as a document for use by Paul in his trial before the emperor), then Luke would have to be dated before A.D. 63, for Acts 1:1 refers to Luke as already written. If Luke used Mark as a written source, Mark would have to be dated still earlier, in the 50’s of the 1st century. If, however, as seems more likely, Luke and Acts were written after Paul’s Roman imprisonment mentioned in Acts 28:30, and Mark was written after Peter’s death, the dates assigned to the Synoptic Gospels will be a number of years later.

According to tradition, the Gospel was written by John Mark of Jerusalem. Early manuscripts thus bear the title “According to Mark.” He was known to be a disciple of Peter, although he was not one of the apostles. Mark is mentioned several times in the Acts of the Apostles and Paul’s letters, where he is identified as Mark, John Mark, or John. He is described in 1 Pet 5:13 as “my son Mark,” perhaps suggesting that he was baptized by Peter. Tradition also holds that Peter is the Gospel’s principal source, providing the eyewitness testimony that underlies the account of Jesus’s life.
The earliest extant reference to Mark as the author of the second Gospel is found in the writings of Papias of Hierapolis (early second century), who calls him the “Interpreter of Peter” and was quoted by Eusebius of Caesarea in his Ecclesiastical History (3.39). Additional attestation was made by Saint Irenaeus (ca. 180), Saint Clement of Alexandria (ca. 200), and Tertullian (ca. 200).
Scholars generally date the Gospel to not long before the destruction of Jerusalem in A.D. 70, possibly during the persecution of the Church in Rome under Emperor Nero. In Mark 13:1–37, Jesus predicts that Jerusalem and the Temple will be destroyed, but Mark does not refer to these terrible events as already having happened.
A date before A.D. 70 is supported by Church tradition. At least one strand of tradition implies that the Gospel was written after the martyrdom of Peter in Rome (between A.D. 65 and 67); the Anti-Marcionite Prologue and Saint Irenaeus, both in the second century, state that Mark wrote his Gospel soon after Peter’s death, although Saint Clement of Alexandria declared that the Gospel was written before Peter’s martyrdom. Finally, Eusebius of Caesarea placed the date for the Gospel even earlier, during the reign of Emperor Claudius (between A.D. 41 and 54).

In these citations, I focused on the Gospel of Mark, which most scholars put as the first gospel written. If you want more from these books, buy them!

LAShort is whats called oral tradition, something the world was very good at when 99% of adults didnt read or write.

I think Homer’s the Illiad and the Odyssey were also memorized and passed down by oral recitation before they were written down. If someone knows the details on that, please correct me. I vaguely remember learning this a long time ago.
