There are many things here that resemble Earth, but at the same time there are a lot of differences. Virgin planet or parallel world? Perhaps our contemporaries will never find an answer to this question. But what if you still try to survive, remembering everything you were once taught or heard about? It seems to work out a lot, so living the rest of your days, and even in relative comfort, is not at all an impossible task. But is this the main thing? There comes a moment when, like Caesar, you approach an inconspicuous river and you have to make a fateful decision. Rubicon. This milestone confronts each of us at least once in our lives, and it’s up to you whether to cross this invisible line or retreat.
