That's fair. We just have different views.
Let me put it this way: if I took a human out of the D&D world and brought them to Earth in real life, they would simply be human. None of the supernatural things they could do in their D&D world would be possible here. Their training and special qualities gained from being a PC, NPC, or creature would be gone completely in most cases or insanely reduced in the others.
For instance, while people survive falls from incredible heights, sometimes with only minor injuries!, the fact a high-level D&D PC could survive fall after fall and fully recover with 8 hours of sleep and rest wouldn't fly on Earth. They'd be fortunate to live through one such fall.
Did you ever see the movie Last Action Hero (not one of Arnold's best movies, but it has its charms)? An action-movie character is brought "out of the movie" and into real life. Suddenly, he bleeds and feels pain, gets tired, and things just don't "work" the way he is used to them working in his "action movie universe". He's still a big, strong guy, though, but just not what he was "in the movie".
That is why I say humans in D&D are just humans. They, in and of themselves, are not supernatural or extraordinary compared to humans on Earth. The fact they live in a "fantasy world", can become PCs, etc. and receive the training involved with their class in that fantasy world allows them to do things we would find supernatural.
