We—humanity—didn’t come this far by being afraid. Explorers and visionaries have willingly headed off to certain death for thousands of years and by doing so brought us to where we are today. No one has ever told us ‘no’ and succeeded in making it stick for long. We accede to these aliens’ demands and we’ll wither away. It may take centuries or even millennia, but we’ll be so busy cowering in fear we’ll forget to move forward. I say we fight.
