That's because Genesis is the tale of the different falls of Mankind and the reason behind the Covenant God makes with Abraham.
Adam and Eve sin, and introduce death into the world.
Adam's son, Cain, murders his brother Abel, introducing discord amongst men.
The daughters of Eve introduce physical degradation of the body by laying with fallen angels and birthing the Nephilim.
From Noah onward the constant, if progressively less apparent, degradation of the Human condition continues in the background, as explained by the narration. Mankind tests God, most reject Him as the curse of tongues hit them, and go on to form their own nations, praising the Fallen Angels that appeared to them yet again rather than their own Father in Heaven.
At this point, Mankind is virtually teethering on the brink of complete isolation from God, which would lead all of them to die with no hope of persistence beyond their flesh.
The Covenant was God's *temporary* solution for this. God *reluctantly* concedes animal blood as an alternative physical price to pay to your own blood, on the caveat that the people chosen by Him to carry out this Covenant abides by a strict set of laws; gentiles, meanwhile, have only the Noahide Laws to abide to.
God, however never intended this to be the method by which Mankind as a whole was to be saved from the grave. God sent Prophets throughout that Covenant to announce someone Daniel call "like a Son of Man", that would sit on a throne on the right side of God after coming out of the clouds of Heaven, and descend on Earth to rid the world of the inescapibility of sin and lay the foundations of the Earthly Paradise to be, when God would literally come down on Earth.
The reason why the Old Testament is boring beyond the Primeval Gistory is because it is a mix of historical records, laws and prophetic messaging that are all essential to each others to keep each other in context.
