Just to be clear - given recent drivel on line - Comet 3I/Atlas is a comet, made of carbon dioxide and water ices and bits of other stuff. It is entirely natural in origin, its orbit is as expected and it will whizz around the sun and then disappear off into the galaxy again. If it ever encounters another inhabited solar system in the far future I hope the living things there are more sensible than us and enjoy it for what it is - a visitor from elsewhere in the galaxy - a pristine lump of rock and ices which formed around a distant, maybe long-dead star billions of years ago and many light years away, just passing through. Isn’t that wonderful enough?
