So we have a belief that the Chicago skyline is below a curved earth and the only reason we can see the skyline is because of atmospheric refraction that produces a mirage of the city skyline.
We have a counter belief that we see the actual Chicago skyline and that it's not a mirage.
Which view is correct?
1. An explanation is not a proof.
2. That it's a mirage is assumed because of a belief the earth is curved and not the result of a test for verification.
3. How do we test or validate the existence of a mirage. In other words how do know we are seeing a real or actual skyline and not one that is a reflection of the real skyline?
I have posted several pics that demonstrate that the actual object above a mirage is the actual object and not a reflection in what is called an inferior mirage.
Superior Mirages

All superior mirages are above the object it reflects like a mirror. A reflection of the object appears upside down. In this pic the right side up ship is real and visible directly under it's reflected upside down image.

Here we see an actual island with an upside down reflected image of it directly over it.
A layer of air beneath an object can produce a reflection of the sky above it making it look like water over land in an inferior mirage. The appearance of water, that looks like a small lake, is the mirage not the object that is above it.

A layer of air beneath an object, like a ship, over water can also produce a reflection of the sky above it. The layer of water that looks like the sky is the mirage and "not" the ship that is above it. Ships over a mirage that reflects the sky will make the horizon line disappear as it blends right into it being the same color. The ship will look like it's floating in air.
When a layer of reflective air is above a ship an image of the ship will always be upside down. When a layer of reflective air is below the ship a reflected image will appear under the ship or their will be no reflected image only a ship that looks like it's floating in air.

Here we see an upright Chicago skyline with an upside down reflected image directly over it.
If the upright skyline in this pic is not the actual skyline we have two superior mirages. But any reflected image above an object, ship or land, will be upside down not right side up. This is an absolute fact. So we must conclude that the actual upright Chicago skyline is visible and cannot be a mirage. Nature cannot produce two superior mirages in the same location at the same time under the same conditions with reflections of and object one upright and the other upside down.
