How Did Life Begin on Earth We Asked a NASA Expert.

According to NASA experts, the origin of life on Earth remains a mystery and is a topic of ongoing scientific investigation and debate. Some theories suggest that life originated through a process called abiogenesis, where simple organic molecules combined and eventually formed more complex molecules and self-replicating cells. Others propose that life may have been brought to Earth through comets or by other means. Overall, the origins of life on Earth are still uncertain, and further research and exploration are needed to provide more definitive answers about how life began on our planet.
