Look at it like this: A pack of wild xorbolorgs.
Savage, slavering xorbolorgs nearing your human home. Trampling human white lawn. Raping your human daughter.
And you can't do shit since they're aliens. The xorbolorg leader grabs your wife and fucks her with his tentacles.
The primal xorbolorgs finally dominate your planet. They watch barbaric shows on 3D projector and you are forced to be their slave.
Such is the downfall of Homo Sapiens.
