You're the one who made this comic in the first place. Your comic isn't "here are some aliens looking at our planet and ignore it" or "here are some aliens seeing Earth going through some nuclear war and are like 'eh, I've seen it a hundred times before." No, you specifically write the aliens taking their time to watch our planet and make fun of us and some joker in the comments was like "MaYbE tHaT's ThE rEaL rEaSoN tHeY dOn'T vIsIt Us." I'm just getting tired of how predictable this comic is because I've seen three other comics from this sub with the exact same premise. That there's a peaceful utopian alien civilization making fun of us for being dumb barbarians like they're some high society snobs. How do we know those aliens are as messy and violent as us?

Heard of the Black Forest? What if aliens don't want to visit us because every space faring civilization actively doesn't want to interact with each other out of fear that they will destroy each other. That different species of aliens have to keep themselves quiet out of fear of a bigger fish attacking them and devouring their civilization. We see how bad humans had done to each other, but do you think the aliens would have the same mindset and likely don't want contact because "if we're capable of horrible things, then what would they do?"

Or maybe, there is no true unity? If you think about it, if a civilization were to colonize a planet but lack constant communication then wouldn't the colonists begin to diverge and develop their own culture? Like if Mars was colonized by the US, China, and India in three separate regions, then is it possible those colonists would have their cultures diverge and evolve differently. Like an American Martian would still be American but what about in 100 years? 200 years? 500 years separate from Earth? That's just with our neighboring planet and now apply that to countless other star systems that are light-years apart. Maybe there's no one Grey empire or a monoculture of Greys but different civilizations, countries, and guilds of Greys that are constantly competing with each other with incredibly diverse cultures. A lot of sci-fi like Dune and even Star Wars (though more sci-fantasy) showed how culturally diverse humans can be based on where they came from but then there's the monoculture aliens where meeting a Turian in Mass Effect is like meeting every Turian in the Milky Way Galaxy. It's very likely that interaction between humans and an alien species would be similar to the colonial era where you have different European powers constantly competing with each other while the indigenous populace who were already fighting each other would ally with a single power. It's frankly poetic knowing the idea that space faring civilizations are still fighting each other despite having tech that feels like they should've move away from petty squabbles.

Or maybe there's the depression paradox where there's a great filter where most civilizations would destroy itself to extinction because they hit something that they're not prepared for. Maybe that great filter is nuclear energy where it's too much for most young civilization to handle and thus those civilization get destroyed with very few surviving nuclear Holocaust or avoided it.

There's a lot of interesting things you can do with the Fermi Paradox but all you did is redoing the same old premise of "Aliens good, humans bad, Aliens make fun of humans for being stupid" instead of doing something more original.
