Ok, I guess I should say "I believe it's most likely that he was a real man", and I base this on my reasoning that myths are far more likely to catch on if there is at least some truth to the story. A complete fabrication means it all started off as baseless words passed from one to another - and I find that highly unlikely and unusual. Stories certainly were passed around by word of mouth back then, but even myths like Hercules were probably originally based on an actual person but without any written record all knowledge of him would be long lost and all we're left with is the myth.
Hmm.... I don't really see it. Nor Hercules for that matter.
Your logic implies that all mythical beings are based on real people. I'm not convinced by that at all.
Zeus, Aphrodite, Thor, the Minotaur, Adam, Eve, St. George (and his dragon), Odysseus, The Flying Spaghetti Monster, Yahweh, Allah, The Green Man, etc, etc, etc.
All based upon real people?
You gotta remember, back then stories were invented to explain things.
Indeed and there is no evidence that the Jesus story is anything other than a made up story.
Also, stories were embellished not only to make stories more interesting but also easier to remember. There is evidence that the city of Troy did exist, but the actual details are by now long lost and the existence of Troy may be the only truth in the myth of the war.
But your reasoning would indicate that all the main characters were based upon real people - Helen, Paris, Achilles, etc.
Likewise, the entire Christian religion may in fact be based on the life of a hapless schizo.
It might. It could just as easily be based upon a completely fabricated life of someone who never actually existed.
For the record, I'm not convinced either way. He might well have existed but the complete lack of evidence suggests otherwise.
