MAJOR new discovery on Mars:
As spirit reached the top of the hill he has been climbing for the last months, the front camera spotted several strangely looking rectangular rocks, each of approximately the same size. Closer inspection revealed inscriptions on what appeared to be these tablets. What Spirit in fact discovered was a complete transcription of "The Monuments of Mars: A City on the Edge of Forever" on those tablets! It appears that in a distant past, mankind went to Mars and ordered the obviously impressed Martians to build statues to honour them. Furthermore we learnt them the metric system and a cultural leap towards the building of large cities. During some apocalytic event on mars, all Martians were killed and mankind had to return to earth. But the knowledge on this events wasn't lost. It silently passed from generation to generation. One man still knew of these events, and even managed to reproduce the contents of those tablets. Amazing!
So you were right after all Fram, it was us who taught them.
