Evidence supporting the idea that water on Earth may have originated from comets includes the detection of specific isotopic signatures in both cometary water and Earth's oceans. For instance, studies have shown that some comets, like Comet 67P/Churyumov-Gerasimenko, contain water with a deuterium-to-hydrogen ratio similar to that of Earth's ocean water. Additionally, computer models of the early solar system suggest that the heavy bombardment period, during which numerous comets struck the Earth, could have delivered significant amounts of water. Furthermore, the presence of ice and organic compounds on comets reinforces the hypothesis that these celestial bodies played a crucial role in providing the water essential for the development of life on our planet.
