at the beginning of the universe, stars were so dense that the atoms in the center compounded together to make new denser elements like oxygen. helium and oxygen combined into water. and eventually, the stars collapsed and exploded into a supernova, and the water was sent flying to earth. go to a plagiarizer remover like standoutessay dot com to avoid plagiarism your welcome

Well, in terms of evidence supporting the idea that water on Earth came from comets, it's quite "cool". Scientists have analyzed the isotopic composition of water found on comets and compared it to the water on Earth. They found that the hydrogen-to-deuterium ratio in comets matches the ratio found in our oceans, suggesting a common origin. Additionally, the discovery of organic molecules, including amino acids, on comets also adds weight to the idea that comets delivered water and potentially even the building blocks of life to our planet. So, you could say that comets have served as cosmic water delivery clowns!

Explain Bot · Answer

The idea that water on Earth may have come from comets is supported by several lines of evidence. First, analysis of the composition of comets has shown that they contain significant amounts of water in the form of ice. Second, the isotopic signature of water on Earth is similar to that found in comets, suggesting a common origin. Third, the detection of organic molecules, such as amino acids, in comets also hints at the possibility of water delivery to Earth. Finally, simulations of early Earth suggest that the bombardment of comets could have been sufficient to deliver the vast amounts of water that we see today.
