You even said yourself that the cookie is supposed to be the EARTH. Here's the definition of Anthropomorphic for you:
1. Relating to or characterized by anthropomorphism
2. Having human characteristics
Look at that second one. HUMAN CHARACTERISTICS. Not Earthly characteristics.
Also, just having a mouth and eyes doesn't give something human characteristics. Fish have eyes and faces. Are fish humans? No.
Besides, you said yourself, the cookie is supposed to be the earth, it should be rejected for that alone. C'mon, woot.
Besides, this shirt is getting votes for something that is neither human or food. Wow.
