How cool would it be to directly image artificial light on the "dark side" of a planet (like all the photos you see of lights on earth at night)?

I mean, even if there is life it's like 1 in a gazillion. But you could imagine some ML looking through all of its images to find planets, etc.

Or imagine another civilization looking at our lights with their telescope

And imagine that the only reason, the ONLY reason, they haven’t completely blown us away, is because our planet happens to be one of the very rare planets where the ratio of the size of our moon and earth is in such a way that you can witness a total solar eclipse as a black hole in the sky once a year, and they would like to witness this event someday.

That's no reason not to blow us away, eclipses still work if there are no annoying humans around to see them.
