Historias de Moderngreekgods

The Greek gods in general honestly don't mind modern times. Sure, a whole lot less people believe in them, and that greatly reduces their powers, but it saves them time since they don't have to talk to priestesses, or help heroes kill monsters, or make earthquakes to swallow pesky mortals. But one day, in the middle of breakfast (I know, right? The blasphemy) aliens arrive. And the aliens have their own gods. And their gods are stronger, because the aliens actually believe in them. And so a mix of different gods from different pantheons embark on a quest to make humanity believe in them again. Unfortunately, times have changed, and that won't be as easy as it was thousands of years ago.

Where are the old gods in this modern age? And how have they changed? Not exactly a poem but not exactly a story either.
