We have no idea if it's universal or not. You being able to imagine something does not mean it's actually possible

That's a terrible counterargument for aliens having moral systems incompatible with humans... because it applies to the existence of aliens as well!

You might as well as argue "we have no idea if aliens exist, being able to imagine aliens does not mean it's actually possible there are aliens", and you'd be technically right... right until the day we meet aliens.

Your line of thought is tantamount to "one should just close your eyes and cover your ears" towards the possibilities in this universe.

Note, I am not a conspiracy theorist and do not believe aliens have visited earth and abducted people or something stupid. But I find it extremely stupid to assume aliens would have familiar moral and ethical systems compared to humans, considering how extremely different human beings already are, and at least humans are all mostly similar! This is similar to european explorers being confused at matriarchal family systems when they meet some random tribe. If some humans cannot even wrap their head around matriarchy, how naive would it be to assume that the average human could be comfortable with alien ethics?
