The universe is vast with millions of galaxies and planets, but Earth is the only known home to life. Humans, existing for 200,000 years, explore other planets in search of life. The "Great Filter" theory proposes that complex life is rare due to challenging evolution stages, acting as filters. As Earth faces challenges like environmental shifts and wars, a crew led by Alexa launches a spaceship to Mars during nuclear explosions. They question whether to stay on Earth or leave for Mars to ensure human survival, reflecting Robin Hanson's concept of The Great Filter.
