You're still forgetting. This is a game. Nothing says there explicitly must be a way to prove everything scientifically. And we cannot use the argument that the logo on the box is unrecognizable to us, in order to conclude that the game is not Undertale. Using the same logic, we could say that the red soul portrait on the generator in the True Lab is actually Chara's soul, since it looks like it.
