Yeah I assume OP intended to imply that you have some kind of significant influence on the actions taken by the aliens.

A regular alien won’t be able to do jackshit about it

You’d have to organise, protest, vote, zlorp, boycott ⟟⋏⊬⏃⏁ etc.

and you probably won’t have much time

At least you’ll know reincarnation is real

After they nuke earth you could go to a few alien maternity wards and interrogate every alien baby on the off chance one of them is someone from earth you know

or just do whatever their version of gooning is
