How do you think aliens would regard our society? If an alien ship landed in your backyard, would you run away or bring a bundt cake?
I guess that means I'm the alien. Hence: I come in peace, I guess?
(Disclaimer: yes, I have Googled it. I still don't get why we'd give one to an alien - does it have some significance? I guess it's just a case of "insert random foodstuff here")
