One of the worst cases i've ever seen was about 20 or 30 years ago. In his novel Chariots of the Gods
Erik von Danikan poses a tendentious question which he posed as though it were rhetorical. There are huge carvings on the rocks at Nazca in Peru, and he was trying to suggest that they could only have been laid out from above.
Well, a bunch of jokers got a grant from the National Institutes of Science, and went down to Peru to see if they could construct a hot-air balloon using the materials which were available naturally, using stone age tools. They actually succeeded. They were filmed by a crew from the Public Broadcasting System.
The question arises, how could people in a hot-air balloon communicate with or control people on the ground? Furthermore, with today's technology--helicopters and radios, for example--how could you control a bunch of primitives carving a huge rock plateau? Well, there is an answer--you don't have to. You can use grid transfer . . .
You take a drawing, you lay out a grid over it, and then you construct a much larger grid, and copy the image from each square of the smaller grid into the larger grid. That, in fact, makes much more sense than loony claims about aliens flying around controlling primitive people on the ground.
It bothers me that alleged scientists are so dense that they would fall for von Daniken's goofy rhetorical trick. What bothers me more, however, is that NIS and PBS are paid for by the tax payer. Nice, expenses-paid vacation in Peru for the NIS grant-writers and the PBS crew.
