This image was famously attached to the Pioneer spacecraft. The idea was that if extraterrestrials happened upon the craft they would learn something about its designers.
After having listened to materialist arguments for many years, I must sadly conclude that NASA failed miserably here, having sent the spacecraft on a fool’s errand. The materialists have insisted repeatedly in these pages that there are no objective indicia of design on the spacecraft from which an alien could distinguish the craft as a whole — or the image attached to it — from random space debris. I don’t know about you, but I am outraged that NASA would squander hundreds of millions of dollars of taxpayer funds on such an obviously quixotic quest.
