Hello Solarwave,
Ted is giving you good admonitions.
Now as to the geneologies, they are listed in the real book of Jasher, too. There are times that a generation is skipped for simple reasons that one who studies can learn. For instance, Moses was the fourth generation from [edit] Jacob, but seemingly the fifth, when looking at his father, but his mother was the daughter of Levi, so he is the fourth from Jacob
The same goes for some others who were descended one generation on one side, but perhaps two or more on the other, due to the long ages people lived. God counted Moses as the fourth generation from Jacob, through his mother.
Also, as to the Word of God being true, there are things in the "Bible" =collection of books, that are men speaking, not inspired, but they are recorded faithfully by those who heard them. In those instances it is not "thus saith YHWH", but "thus said so and so". If the Word does not agree with their statements, then that is clear to those who study the Word to see what is "Thus saith YHWH", that the speaker was speaking from their own belief or wisdom. But you cannot apply that to the Torah, for it is "Thus saith YHWH".
Also, most of Enoch is "Thus saith the LORD of Glory" -even through His ministering angels who showed Enoch things that were total truth about the creation. There is a fragment in Enoch of the book of Noah, and in that book, Noah laments "writing" as a labor heavy upon him not meant to be. Solomon also lamented the same, so the two gave their opinions, not God's.
When God said to the prophets to write, they wrote His truth, and when Moses wrote Genesis, he wrote the Word of the LORD, and not a fairy tale with no meaning.
Here it is: Jacob went into Egypt, and in the fourth generation from Jacob, Moses led Israel out.
Gen 15:16 But in the fourth generation they shall come hither again: for the iniquity of the Amorites [is] not yet full.
Jacob
Levi
Exd 2:1
And there went a man of the house of Levi, and took [to wife] a daughter of Levi.
Exd 6:20 ¶ And Amram took him Jochebed his father's sister to wife; and she bare him Aaron and Moses: and the years of the life of Amram [were] an hundred and thirty and seven years.
Num 26:59 And the name of Amram's wife [was] Jochebed, the daughter of Levi, whom [her mother] bare to Levi in Egypt: and she bare unto Amram Aaron and Moses, and Miriam their sister.
And the age of Jochebed when she bare Moses is in Jasher.

Anyway, counting generations is not easy, but one needs to study to see when a generation is skipped because of coming through a mother who is a generation closer to the patriarchs than the father is.
In Jasher chapter 5 we read that at age four hundred ninety eight, Noah married his great grandfather's daughter, "Naamah the daughter of Enoch, and she was five hundred and eighty years old". -Now we've skipped three generations counting the sons of Noah through the mother, from Enoch.
Then Noah took the three daughters of Eliakim, son of Methuselah, for wives for his sons, as the Lord had commanded Noah.
Now the children of Noah's children are, through their mothers, are skipping two generations, Lamech and Noah, so the grandsons of Noah are only two generations removed from Enoch, through their mothers. -I needed to think that one through -whew!
Reading shows lots more like that, but you have to read and study to correlate the Scriptures with the Scriptures.
