Meat eating ethical?

[Anomalocaris]

So, if a superior alien race came to earth, would it be ethical for them to eat us?

You seem to imagine ethics is some sort of objective thing whose form and existence is a material objective fact that would be perceptible independent of whether it is you, or an alien race, that is examining it.

In fact it is by fundamental nature an artifical mental construct for the convenience for its creator.

Our convenience and those of the alien race would not be the same.

It would be inconvenience for us to be eaten by aliens. so we can scream that would be inethical. It would indeed be unethical for us.

But there is no reason whatsoever that aliens need or should be perturbed by our convenience. If alien form ethics for the same fundamental reasons whu we do, then all they will examine is by showing us mercy, it is within the realm of plausibility for us to recpricate in a manner noticeable or desirable to them.

If not, there is absolutely no reason why it would be inethical for them to eat us.

If we want to make it unethical for aliens to eat us, think about how we can hurt them if they do, or help them if they don't, in a way that matters to them.
