What if aliens are not friendly? /sarc off

[Scythian]

They recorded the horrifying sound, warning, this is disturbing ...

Space Roar

[Scythian]

They decoded the sound, the message is repeating and says over and over again ...

I have become death destroyer of worlds ....

"What if aliens are not friendly?"

If they in fact exist, and if our own planet's history is any indication of how things turn out when advanced civilization meets primitive society, we are toast. I fully expect they won't be friendly at all. The Europeans didn't sail across the storm-tossed Atlantic to the Americas just to shake hands and say "Howdy!"
