There is no reason to think aliens even exist, let alone come here in flying saucers. People see a blob of light in the sky that is really an aircraft or balloon, something like that, but in their mind they pretend they are watching an alien craft. The reason they glow? The objects that aren't reflecting light, don't get noticed and reported as flying saucers!

That's a really good question. From everything I have ever learned about UFOs they can hover completely silent and without lights. We use lights to see and/or be seen. I doubt alien crafts rely on external lights to see where they are going, their navigation equipment would be far more advanced than that. So the only other logical reason would be to be seen. We can only assume they want us to know of their presence. We can only guess at the reason for this.
