An ancient Chinese plate of observed comets. There may have been more comets in the past, as the body whose remnants today are Comet Encke and the various Taurid meteor streams, is estimated from projectories to have contained far more mass when it first entered the solar system ~ 14,000 years ago. All the mass was lost as the gravity of the Sun and the larger planets tugged at the initial body and its components, creating fragments that themselves were pretty big and apparently impacted somewhere - maybe here. Maybe at Saginaw Bay, splattering mountains of glacial slush over the areas where we now see northwest-pointing shallow ovals, which can be miles across, called Carolina Bays (thanks to Google Earth), in the Carolinas and neighboring states and also in midwest, where they point northeast This is not accepted science but great internet speculation. Anyway, note the image at the bottom right, which resembles a notorious political symbol of the 20th century that itself was based on an ancient widespread motif in Eurasian pottery. This image is in fact a head-on view of a comet, a head-on view! This is not something you want to see in the sky. This may be the origin of the notorious political symbol, ironically a symbol of ancient dread, an omen of evil, the portent of an impact event.
