Researchers at Oxford University have challenged the prevailing theory regarding the origin of water on Earth, suggesting that it did not come from asteroids as previously believed. Instead, the study indicates that the materials that formed the planet were significantly richer in hydrogen than earlier estimates. This revelation could reshape our understanding of how water accumulated on Earth, with implications for theories about the planet's early conditions. The study highlights the possibility that water may have been present on Earth almost since its formation, contradicting long-held beliefs about its extraterrestrial origins. The findings were part of a broader investigation that also examined the role of marine phosphorus in the planet's oxygenation process approximately three billion years ago.
