1) The point about the foil shape was that its essential to create lift in order for the object to fly. It is key to knowing what it takes to fly and that object proved they had that knowledge. I did not say they didn't have a way of figuring that out by looking at birds because they could.
2) Yes, planes like the B-2 Bomber can fly without such but wouldn't it be safe to say that the overwhelming majority of all planes posses some sort of rudder or vertical stabilizer. I did say nothing occurs naturally, like the birds for the foil shape inspiration, to inspire them for the rudder idea. That is something they would've had to figure out through design.
3) I'm speaking from my mind and not running to Google so I can make a post. Whoever made the artifact is irrelevant to my point and I stand corrected.
