Faced with the blank canvas of outer space, we’re all, to some extent, toddlers with a fistful of crayons. Our imaginations run wild when we think about what we could achieve with other planets. We could leave this trash-can planet behind, with all its wars and climate change and corrupt politicians, and start over. Earth doesn’t have to be the main event but rather a rehearsal for utopia. It certainly sounds easier than trying to fix the mess down here.
