Blood, I don't know what training you might've had in literature, but type "oldest English story" into google.
Beowulf.
Beowulf has a lot of historical characters in it (or at least characters based on historical figures. More so, we are talking about a work that was not meant to be a historical account in the first place. So it really doesn't give a good comparison to the Gospels, which are presented as historical works).
We can look at one of the earliest known literature pieces, the Epic of Gilgamesh, and see that again, there is a hero, but it is based off of a historical figure.
That is a common theme in ancient works.
No. It really doesn't matter much. Put on your thinking cap and become the writer of a hero story. No... really... try to imagine it.
Is your hero story based on a physical human being? Well, maybe or maybe not. You might remember some story from your childhood which your father told you. You might misremember the story, but you're pretty sure that your dad had a buddy during the war who performed many outstanding feats of courage.
So is your story based on an historical figure?
What could such a question possibly mean.
If the story is based on a historical figure, then one can not call that figure made up. Was the story of Jesus exaggerated, and did myths enter into his story? Of course. However, we see the same thing with various other historical figures from that time. Such as the Emperor Augustus and Alexander the Great (the only writings we have of the life of Alexander that Great, also come long after he was dead).
So is the story based on a historical figure? Yes. Is it 100% accurate? No.
OK. And young men feel no particular passion for young women.
Whatever we want to say, we can say.
No, you need evidence behind your statement. I'm not denying that people have a passion for heros. What I'm denying is that this passion would cause a person to fabricate a hero, instead of looking at the various heros of their time. A hero does not need to be mythical.
