Marsha

Despite living on Mars, she refuses to believe in "aliens". Her friends even showed her pictures of Earth, with strange creatures in "Hawaiian shirts" and "flip-flops". But Marsha just scoffed, "Cute animation, guys, but I'm not fooled. Show me an actual green, four-armed, space invader!" Indeed her staunch disbelief would amuse the Universe forever, making her the first Martian in history who didn't believe in Earthlings.
