Is there any evidence that they are either lighter than air or immaterial?

Yes, quite a bit. Some of the most compelling, perhaps, comes from astronomy where the interactions of distant galaxies defies all our understandings/models. Arguably other compelling examples are when comets (believed to be made of dust and ice) travel through the sun unscathed.

The fact that they consistently float above and never fall is a good evidence, in and of itself, that they likely cannot be very dense - but this is a bit too obvious for the average “educated” mind to grasp. To the uneducated or the properly educated, it is a perfectly reasonable assertion - however.

If they are immaterial, where does the light come from?

The air they are comprised of/surrounded by/interacting with! There are some intriguing videos of people showing that a combination of a just a few ionized gasses is responsible for the primary spectrum of colors in daylight.

Of course, your next question could/should be - where does the power come from to ionize the gasses... That is the real question. Sadly most questions don’t have answers, and the contrived answers we are taught to believe, in lieu of the correct answer, are consistently (and wildly) wrong generation after generation. You learn to live with it ;)
