Historically, many thought the large lava plains on the Moon were actually oceans. Which is where we get such names as the Sea of Tranquility.

Excerpt from a short story I'm trying to sell:

"Humans believing there's some alien structure on Mars has a long history," said Barstow, hoping to change the subject. "Lowell seeing canals. The face and the pyramids. The spoon and all those other odd rock formations the landers found. All optical illusions or coincidence. We were cynical about the existence of artifacts on Mars long before we actually got someone here. Then came the Fifth Manned Mars Mission. Which had a neutrino detector on board. When it spotted a large void where no neutrinos came through that was dismissed by many as a problem with the instrument. Only it wasn't."
