In order to "see" something with eyes, the object must be longer than the light wave refracted from it. Molecules are too small to be refracted.
we see things when a light source goes into our eyes or when it reflects off an object
UV bulbs usually have a coating on the inside that glows when the light is on, providing indication in the visible light part of the spectrum.
Not directly. Light is a by product of heat. So anything which produces light is a visible indication of heat. Heat can also produce a shimmering effect as it aggitates air molecules changing the airs density which is visible to human eyes.
Individual molecules are too small.
It's about wavelength and size. The wavelength you use to look at an object has to be shorter than the object. And visible light has a wavelength that is longer than a molecule.
If your vision is normal, then you CAN see visible light.

because light used to see an object must have a wavelength
No. Atoms and molecules are far smaller than the wavelengths of visible light, so light cannot be used to image them.

Visible means "what you can see" - so yes.
Air does not absorb or reflect enough light to be visible, regardless of what temperature it is.
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
The advantage of visible light is that you can see it. Also, because our eyes are sensitive to light you can see colors. Violet has the shortest wavelength and red has the longest. Visible light is the only EM waves that you can see.
