A message from Alpha Centauri

Following a recent governmental lapse in Truth, a scrambled message has been intercepted and somewhat decoded. The communication details an alien overthrow of humanity. Elf Wax analysts were able to decipher certain parts of speech and published them. The translation, in its original form follows:

I am from Alpha Centauri, a star of dead rocks.
I am from another dimension. Another time.
You have lived too long. Your bad vibrations are polluting our air waves.
It’s time now. It’s time to burn. We’ll burn you and your sons’ sons. And then we’ll burn up the sun.
With hungry eyes, we’re looking at you lucky few.
