So did the space aliens provide the wooden balls and rails, or just the plasma beam weapons to make the wooden balls and rails? Boy, this stuff gets confusing fast.

These balls are from the first ever baseball game - each stonehenge stone was a base. Most bats have disintegrated 'cause they were made of wood - however if you need proof of this - a disgruntled team did throw a few of their bats into a nearby bog - I'm sure they are still there, if you look you'll find them!
