The early astronomer Percival Lowell looked at Mars through telescopes and saw patterns on the planet's surface. He came to the conclusion that they were evidence of canals and planted crops.

Twentieth century unmanned probes proved conclusively that Mars wasn't home to an advanced alien civilisation.

While today's mainstream scientific theories about the Solar System aren't quite as colourful as Lowell's, future scientists will no doubt prove some of today's theories wrong.
