Replying to the OP's last post, I think that is honesty on his part. In the life of an unbeliever satan has succeeded, and only when we attempt to turn to the Lord does any battle take place, trying to discourage us from it. satan's greatest success is when we think he doesn't exist, and the OP is clearly not actively turning to the Lord, so I have to respect his POV.
11. Where did Satan the angel fall from?
12. How far did Satan fall?
13. What caused Satan to stop falling?
He fell from heaven, to earth. Earth is classified as being between heaven and hell, so in the grand scheme of things over all time, satan has not stopped falling yet. This is depicted in Scripture as "Babylon is fallen, is fallen." (Which is why I view "the second death" not as annihilationism, but a continuing existence.) satan best approaches temporarily not falling further, by being glorified in humans who embody his will. This is MUCH more an everyday occurrence than almost any of us are really aware of!
14. Why is Satan anthropomorphized as if he were human?
I will address this whole concept giving it some merit. First, yesterday I posted much detail in this sub-forum in a thread started by "curious atheist," and I am trying not to cover that same ground here. Second, humanists also say that G-d Himself is also anthropomorphized. Please recognize your "why" answer is that the language in Scripture is not G-d Himself, but is Him trying to get His point across being aware of our limitations. How better to do so?
16. Does Satan have any physiological characteristics?
The topic here is you do not know what is meant by "spirit." It may be helpful to recognize that first of all, it means having no body. So if there were to be some actual incarnation of satan a la Rosemary's Baby or something, it would no more be satan's body than Jesus gave G-d actual hands. (Although in a sense He does, and continues to)
17. How did Satan come into existence?
I do address this in the other thread I mentioned, which again goes beyond the confession of our Faith but I think employs sound reason based on what is revealed via Scripture. Bottom line here is what is left unknown is intentionally given as a sobering warning!
6. Is Satan male or female?
Traditionally He is looked at as male.
I think this is just because of culture of the day, which partly denotes his authority. Culture hasn't changed that much, because attributes like anger and nastiness are still stereotypically male, even though females really aren't automatically free of such evil. Again, as spirit there is no gender; that is a physical trait.
20. Allow me to reword. What human(s) first documented the existence of Satan?
21. What caused these humans to come up with the concept of Satan?
My final answer on that is Job, which I hold to be the oldest book in the Bible. It says basically everything it has to say about satan right in the first chapter, and I think this directly addresses yin and yang, declaring it to be false even though it was the highest wisdom of it's day, and G-d to be a higher wisdom.
It was written because G-d loves mankind, wants to reveal Himself to us, and enjoys our company.
22. Did Satan appear to Adam and Eve as a human?
This is actually a good question, because he did not "go upon his belly" before Adam and Eve's judgment, the same day as their fall. (Which could have been millions of years after they were created; the Bible does not specify.)
The answer to your question is unknown, and I see no basis upon which to even speculate.
23. What was the agenda of those who first posited the concept of Satan? What were they trying to convey?
This is a repeat of 21.
