Are there any famous people of the past that are accepted as real, or their deeds as true, but in historian circles are considered more likely to be fable?

I was thinking of the time we are in now with falsified news articles, government propaganda or the bent truths by celebrities for PR.

For example, if we weren't so good at documentation and records these days, maybe in the future everyone would think forrest gump was real.

Edit : fable is not the right word, but you get what I mean

Founding myths are the most easy targets for things like this. There are numerous myths about George Washington for example that have not a lick of truth to them. I would say that these are probably the closest to 'modern' fables outside of conspiracy circles.
