Impossible Earth theory

The Impossible Earth theory supposes that the Earth and humans represent an astronomically small chance that intelligent life would emerge on a world in the universe. The theory supports a notion that the universe is fine-tuned twice: once to support matter and twice to support life. Some have suggested that the universe is fine-tuned three times to support the emergence of human-life or human-like lifeforms throughout the universe. The theory is an evolution of the Rare Earth hypothesis.
