Is there life on Earth? From a Martian perspective, their scientists discover that humans have four wheels, guzzle fuel and basically just party through life before undergoing the ultimate process of recycling/sex! This animation is great fun, as is the narrative - it pokes fun at the simplest of activities we do in our cars - petrol stations, traffic jams, car washes and it even attributes human traits to the humble traffic light! Accompanied by a swinging soundtrack, this is well worth a watch, as the Martians wonder what is the purpose of an "Earthling"!
