This analogy crucially omits the shape of the ear itself.
Do the experiment

The barn owl is one of the most widely studied animals for sound localization. It has been shown that the barn owl has the best ability to accurately localize sounds out of all the species that have been studied. The barn owl’s left ear is higher than the eye level and points downward while its right ear is lower than the eye level but points upward. This unique anatomy gives barn owls exceptional ability to localize sounds in the vertical plane.The last time I looked in the mirror, my ears were symmetrical. The fact that this bird requires such an adaptation rather proves my point!
There is no point arguing
