Intervention: How Humanity from the Future Has Changed Its Own Past

Scientific evidence suggests that time travel is not only possible but has already occurred, influencing key events in human history. The author presents a theory of 'intervention,' where time travelers—some known, others anonymous—have made crucial alterations to our environment, such as the creation of the Moon and the extinction of the dinosaurs, to ensure the development of intelligent life. These interventions were strategically placed within the timeline for future generations, providing markers for humanity’s progress.
