First of all, ask yourself "Are there really aliens?", "Has anyone REALLY seen an alien?". After you've gotten the answer, then you can begin to ask if aliens kill. But to answer your question, if there are really aliens, the question of whether they kill or not, will depend on what they think of other life forms. Are they superior to them? Can they be anihilated? In a nutshell, more questions, lead to more questions, but the ultimate question remains...do aliens really exists?
This question makes no sense. If people could prove whether or not aliens exist, then conspiracy theories would be a thing of the past. Again, this question makes no sense.
no aliens are from other planets (whether they exist or not) and jinns are spirits on earth.
No aliens are known to exist, so your question is unanswerable.
No aliens are known to exist, so your question is unanswerable.
They feared if the Aliens, would remain loyal to the United States.
Aliens are not known to actually exist, so your question is unanswerable.
The oldest unanswerd question is "are there aliens"
Any you wish.
First we have to know whether or not they exist.
No! Why ask such a stupid Question he does not WORSHIP Aliens plus they don't exists.
It doesn't matter whether they're illegal aliens: you can evict anyone you want to for good cause.
