As a Jew, who is familiar with the Books mentioned in the Mikra, specifically in the Torah, we know for a fact a Book existed before God gave Moses the Torah. This Book was in existence to the Jews even after God gave Moses the Torah and it not only covers the same thing God told Moses in the Torah but it even goes deeper into detail. And even though the RCC did not accept it for the Canon [
they believed it was LOST but the Jews had it hidden], Jews don't go by what the Gentiles think on which is Canon and not. The Jews know the Canon the Gentiles use today doesn't even completely match the true Hebrew Old Testament which God gave to the Jews.
But I am not here trying to make this relevant only to say you mentioned Enoch and we do have materials that fill in the blanks about Enoch our current Book of Genesis does not cover. And this Book was mentioned as Book of TRUTH by both Joshua and King David, which is the Lineage Jesus came from. I am obviously talking about the Book of Jasher.
So let's look at what Jasher tells us more about what Enoch did or not do.
1 And Enoch lived sixty-five years and he begat Methuselah; and Enoch walked with God after having begot Methuselah,
and he served the Lord, and despised the evil ways of men.
2 And the soul of Enoch was wrapped up in the instruction of the Lord, in knowledge and in understanding;
and he wisely retired from the sons of men, and secreted himself from them for many days.
3 And it was at the expiration of many years, whilst he was serving the Lord, and praying before him in his house, that an angel of the Lord called to him from Heaven, and he said, Here am I.
4 And he said, Rise, go forth from thy house and from the place where thou dost hide thyself, and appear to the sons of men, in order that thou mayest teach them the way in which they should go and the work which they must accomplish to enter in the ways of God.
5 And Enoch rose up according to the word of the Lord, and went forth from his house, from his place and from the chamber in which he was concealed; and he went to the sons of men and taught them the ways of the Lord, and at that time assembled the sons of men and acquainted them with the instruction of the Lord.
6 And he ordered it to be proclaimed in all places where the sons of men dwelt, saying, Where is the man who wishes to know the ways of the Lord and good works? let him come to Enoch.
7 And all the sons of men then assembled to him, for all who desired this thing went to Enoch, and Enoch reigned over the sons of men according to the word of the Lord, and they came and bowed to him and they heard his word.
8 And the spirit of God was upon Enoch, and he taught all his men the wisdom of God and his ways, and the sons of men served the Lord all the days of Enoch, and they came to hear his wisdom.
9 And all the kings of the sons of men, both first and last, together with their princes and judges, came to Enoch when they heard of his wisdom, and they bowed down to him, and they also required of Enoch to reign over them, to which he consented.
10 And they assembled in all, one hundred and thirty kings and princes, and they made Enoch king over them and they were all under his power and command.
11 And Enoch taught them wisdom, knowledge, and the ways of the Lord; and he made peace amongst them, and peace was throughout the earth during the life of Enoch.
12 And Enoch reigned over the sons of men two hundred and forty-three years, and he did justice and righteousness with all his people, and he led them in the ways of the Lord.

As we clearly can see, Enoch, chose to serve God and despise the evil ways of men and he even went to a remote place to be far away from men so he could be alone with God.

Once again, what Enoch did is proven in Acts 17:
26 And he (GOD) made from one man every nation of mankind to live on all the face of the earth...
27 that they should seek God
And Enoch did exactly like Acts 17 describes and the Book of Jasher also verifies this
