The world that see you when looking out through your eyes doesn't exist in reality either. It's just models your brain puts together from some sensory stimuli (photons hitting your retina), but they aren't real, they are mere concepts that happen to work well enough that you may manage to live long enough to procreate... they were made by evolution, and evolution doesn't care if it's real so long as it works well enough. I don't think it's meaningful to say that the electron described by QM doesn't exist in nature... something exists in nature and all we can ever do is describe it with a model.
