Actually any choice we make creates a new unique timeline where different choice(like stepping on butterfly) will make radical changes in the future, diverging from mainstream timeline. As in Sci-fi time travel which changes the past a little, leading to enormous changes in future: this is the past, and we are shaping the future with our choices. Would it matter in far future if sun is destroyed, if we choose to invest in space expansion and colonize new systems? The future isn't set in stone, fatalism is just learned helplessness, robbing us of free will and drive to improve our condition.
