Back in the 1950s and 1960s settled science said there were Canals on Mars! If you did not believe it you were laughed at in school. SETTLED SCIENCE!
I still remember a book from a 1950s writer who met with spacemen from the planet VENUS.
I remember ads in magazines telling us of the holes at the North and South Poles of the Earth and people living in THE HOLLOW EARTH.
“writer who met with spacemen from the planet VENUS”
When the aliens tell you they are from Uranus...
Run!
