19. There are Canals Found on Mars
Percival Lowell, who is an author and one of Space’s first popularizers, wrote many books back in the early 1900s. In some of these books, he writes about all the canals that were built on Mars by intelligent civilizations.
He thought that they built these canals in order to move water into the more deserted areas of the planet. He came to this conclusion because he stated that he saw all this happening through his telescope, which we should all know isn’t true.
The only things that are closely related are small channels, created from nature, but hold no water.
