These are the odds of “you” being born… 1 in 1,100,000,000,000,000,000,000,000,000 Think of the chain of events that had to align for you to exist: A Sun-like star with an Earth-sized habitable planet (≈ 0.2–0.5 chance). That planet stays stable for billions of years (≈ 0.1–0.5). Life begins at all (abiogenesis ≈ 10⁻⁶ to 10⁻¹). Life evolves into complex organisms (≈ 10⁻³ to 10⁻¹). Conscious, self-aware minds emerge (≈ 10⁻⁴ to 10⁻²). Your parents meet and have a child (≈ 10⁻⁵ to 10⁻²). Conception happens in the one cycle that produced you (≈ 0.25).
