Where Did Earth's Water Come From?

The origin of water on Earth is a captivating scientific inquiry that has engaged researchers for decades. Several theories attempt to unravel this enigma. One prominent hypothesis suggests that water was delivered to Earth by volatile-rich comets and asteroids during the planet's early formation. These celestial bodies, composed of frozen gases and ice, bombarded the young Earth, bringing substantial amounts of water along with other elements necessary for life. This theory gains credence from the observation of water-bearing comets and asteroids in our solar system, reinforcing the notion that these cosmic wanderers acted as water carriers, shaping Earth's hydrosphere and laying the foundation for life's emergence.
