Some are utterly wrong in thinking there was no writing in the days of Adam and Enoch. Cuneiform tablets in museums and pyramid texts in pyramids attest to the existence of writing around 3000 BC. Enoch was probably writing between 3000 and 2850 BC and Adam died around 2900 BC - writing reached quote an advanced form around 3000 BC. Enoch was one of the first to master writing and his descendants kept it going before and after the Flood. One period before the Flood was marked by a change of writing from vertical to horizontal called the Jemdet Nasr period around 3100 to 2900 BC - https://en.m.wikipedia.org/wiki/Jemdet_Nasr_period - around the time Enoch was king, around 2900 BC. Enoch was king under the king-name En-men-dur-anna https://en.m.wikipedia.org/wiki/En-men-dur-ana . Adam had been king under the name Alulim and died when Enoch was around 300 years old - around 2900 BC. Enoch was translated to Heaven around 60 years after that around 2850 BC and carried on writing and much of the original content of Book of Enoch was written around that time. We have extant texts reporting themselves written by Enoch's grandson Lamech under the king name Shurappak - a city of that name where he ruled is named after him and is very important in archaeology because it still shows the Flood deposits. This writing is for his son Noah - king name Zuisudra - it is found in two museums today. https://en.m.wikipedia.org/wiki/Instructions_of_Shuruppak
The Book of Jasher records that Cainan was writing on tablets of stone (clay? cuneiform) in his lifetime too - religious writings inspired by God - and he died around 2600 BC. He lived almost a thousand years so he might have started writing at the same time as Enoch around 3000 BC. Noah too was writing centuries before the Flood so around 2500 BC. He was born a couple of centuries before Cainan died and his grandfather was Methuselah to son of Enoch so of course Noah would have been well prepared to write scriptural texts (in cuneiform and on stone). The archaeology shows the main school for writing skills after the Flood was a main institution in the city from which Noah is recorded as having ruled. It was named 'city of the book' if I remember correctly - writing was a major part of these first patriarchs' lives even from within the lifetime of Adam - all attested and enlightened by archaeology in the last few centuries. And ancient historians tecord
it too like Josephus and of course the writers of Jasher. Even China has records of this time.
A good checksum to test the chronology is the Book of Jubilees which bacause of the cunning way it is written (reportedly by Moses with a angel dictating it) is very hard or impossible to corrupt with regard to its dates so an excellent verification on this chronology.
The successors of Enoch moved the kingdom capital to Shuruppak - what is Shurappak famous for - a clue is Tel Fara - this is the modern name of the archaeological site of Shuruppak city of Methuselah and Lamech and begore the Flood Noah - what do we find at Tel Fara - clue - a period of this time in history gets named after it - the Fara Period https://en.m.wikipedia.org/wiki/History_of_Sumer - why give it a special name - because this is the time (around 2700 to 2600 BC) and place when writing first captured the full flow of human thought.

Sippar, the capital city when Enoch was king (under the name Enmendurana) is the city in two parts - probably the city mentioned in scripture from much later in its history as Sepharvaim - but see its significance in Enoch's time (Sumerian periods ED I and ED II) https://en.m.wikipedia.org/wiki/Sippar
So there is a possibility the Fara Period in achaeology and known history was actually a direct result of Enoch being 'translated' into Heaven and being taught syllabic writing by angels then bringing that writing back to humans in Sippar where he had been king and teaching it and what he had written about Heaven and Earth.
The oldest books known today include the Instructions of Shuruppak a copy (extant) of which is in a museum near where I work so I'd love to see it. It is a copy of earlier works and dates to around 2100 BC. An older copy still is in a museum in Chicago. This was after the Flood but the earlier work was from before the Flood and is a book of proverbs passed on father to son from Lamech to Noah (known by their Sumerian names). translation: http://etcsl.orinst.ox.ac.uk/section5/tr561.htm
