When my dad was unwell recently, it was because an infection had messed up his vestibular canal, which takes messages to the brain from the labyrinth.
There is one of these pieces of equipment behind each ear.
The labyrinths are a system of tubes at right angles to each other, containing liquid which passes over sensors. They are what tells the brain precisely what angle the head is pointing at and keep us in balance and knowing what way up we are and how fast we're we're accelerating in any direction. You need tubes at right-angles to get full 3D data about movement.
It's because of these that, for example, when we tilt our heads it doesn't appear as if the world has moved.
When one of dad's got messed up, he felt as if the world had tipped up and was spinning. He was convinced of it, and was holding on for dear life to a sink for one hour until paramedics managed to prize him away.
Now: tell me these labyrinths evolved. Sorry mate..... that's beyond all reason and requires the suspense of all logic. That requires belief in the totally impossible. Accepting the clear, incontrovertible evidence of design is the logical response.
