Maybe you can tell me, who did write the Gospels? What does your scholarly concensus (whom ever that might be) say? So . . . . . .what exactly was said long ago?
1. Adam and Eve are not fact. No evidence of their existence exists outside of the Bible, not to mention it flies in the face of all biology for two humans to propogate a species. Even if however you want to go with the route of reality, they certainly would not have been the first humans.
a. You'll notice that Genesis 1, says that God created Man and Woman (not out of dust, and not separate). Genesis 2, has God create Adam and place him in the Garden, followed by later creating Eve. The storie of Genesis can be regarded as either two separate accounts of creation Or the second chapter is an explanation in more detail of the 1st chapter.
The problem with that is that you would need to complete ignore the verse that says "Cain knew his wife" later on in Genesis. The account of Genesis has Adam and Eve producing Cain, then Producing Abel, followed by Cain slaughtering Abel.
So who was Cain's wife? Was it a sister not mentioned? Seth is later mentioned after Abel has passed. Or was it another woman?
If you accept it was his sister, you're more than welcome to, but that would be ignoring biology. Which I'm sure you are fine to do.
2. You of course are ignoring that all those 7-900 year old people...are not fact. As there is no evidence of their existence. There isn't even archeological evidence of the existence of Abraham, Isaac, Jacob or Moses.
The Bible does not say it is the word of God, because the Bible is a composite of books, books that have theological, poetic, historical, and mythological natures. There is no indication at all that these books were supposed to be put together into one book, and even when that was done, there was still not a full consensus on what books belonged there. You also ignore that these were oral traditions. I'm not sure if you ever played the game telephone as a child or perhaps with your own children, if you have you would know that oral communication is unreliable.

3. I also didn't know that you took the book of Enoch as part of biblical theology, because it is rather obvious that is where Revelations is drawing inspiration from. It is the book fo Enoch that speaks of the rebellion of angels.
Since you didn't read the link I put I"ll give post it for you
The Second Book of Enoch, also called the Slavonic Book of Enoch, contains references to a Watcher (Grigori) called Satanael.[17] It is a pseudepigraphic text of an uncertain date and unknown authorship. The text describes Satanael as being the prince of the Grigori who was cast out of heaven[18] and an evil spirit who knew the difference between what was "righteous" and "sinful".[19] A similar story is found in the book of 1 Enoch; however, in that book, the leader of the Grigori is called Semjâzâ.
4. Pre-tribulation rapture theology was developed in the 1830s by John Nelson Darby and the Plymouth Brethren,[12] and popularized in the United States in the early 20th century by the wide circulation of the Scofield Reference Bible.[13]
I wanted to post that because I notice your name was Rapture Era.
You are of course under no obligation to believe any of what I have written here and I doubt that it will convince you to look explore any further.
