a mirage is the refraction of light, like when you put your penis in a glass of water.

It would be just as silly for me to claim that my glass of water is able to bend light around its own mass.

>general relativity says gravity bends light

Yes. By an *incredibly small amount.* So much that it would be completely impossible to see.

The Earth does bend light around it, sure - because it has an atmosphere. This isn't relativity, this is classical optics. All materials bend light - you may have heard of "lenses" or "prisms" which exploit this effect by using highly refractive materials. But all materials refract the light passing through them - water, oil, glass, plastic, and yes, air.

Electromagnetic field theory states that moving magnetic fields create light. But if you were to argue that this means it must be false, because if you wave a magnet around you can't see it glowing, you'd be an idiot. Effects have sizes.
