Did Comet Impacts Spark  Life on Earth?

The impact of comets crashing into Earth's surface may have provided the energy to create simple molecules that formed the precursors to life.

The Journal of Physical Chemistry publish a study that was based on a computer model of an impact's effect on a comet crystal initially made up of water, carbon dioxide and other molecules.

''Comets carry very simple molecules in them," said study co-author Nir Goldman, a physical chemist at Lawrence Livermore Laboratory in California. "When a comet hits a planetary surface, for example, that impact can drive the synthesis of more complicated things that are prebiotic — they're life-building."

Maybe comets did spark life on earth. What do you think? Leave a comment!
