Comet theory in doubt
Computer simulations published in *Scientific Reports* suggest comet impacts on early Earth were generally too fast and violent to deliver intact hydrogen cyanide, a molecule important to prebiotic chemistry. Across 100,000 simulations, 54% had no impacts and the rest had at least one, but successful delivery was considered unlikely. Researchers said asteroids or chemical processes on early Earth remain possible sources of life’s building blocks, while Mars may have offered better conditions for comet-delivered molecules.
