2. Meet Marty the Martian

3. Marty was sent to Earth by the Martian government to find life.
Marty captured a car and brought it back to Mars.
Marty must stand trial to determine if he met or failed to perform his Martian duties.

4. At the trial, Marty said:
“I first saw these life forms rolling along roads in great numbers.
They were giving off thick clouds of poisonous waste as they moved.
They seemed to exhibit herding behavior, as many of the cars moved in the same direction.
They appeared to have a great deal of energy – some of them moved greater than 60 km/hour!
When one of these life forms stopped or slowed down, the others behind it responded. They slowed down and gave off a reddish light from the back, and sometimes they made honking noises.
I observed that they stopped to feed on a liquid substance.”
