Because the universe, which we are born from and live within briefly, is not fair.
A single instant in time which we do not understand led to an unimaginable expansion where the tiniest of fluctuations at the quantum level led to matter randomly collecting and coalescing into stellar clusters of billions of galaxies with trillions of stars with planets, and we know of only one that led to life.
Fairness, a completely human societal concept, has no impact on the reality of our universe and unless you can change that, life will never be fair.
