How is Earth's water older than the Sun ? Hi, My name is Aman Peace. Allow me to articulate my perspective on this matter: I posit that prior to the formation of the axis upon which our Earth currently rotates, and even preceding the formation of the sun itself, there may have been a phenomenon wherein water circulated. This notion finds support in recent astronomical discoveries, such as the detection of water vapor on the exoplanet GJ9827d by astronomers employing NASA's Hubble Space Telescope. Given that GJ9827d boasts dimensions roughly twice that of Earth, it presents the tantalizing possibility of harboring a water-rich atmosphere. Consequently, it is conceivable that in the locale where Earth's formation occurred, water or water vapor may have predominated initially. However, with the advent of the sun's formation, gravitational forces attracted asteroids towards it. Prior to these asteroids coalescing with the sun, they could have absorbed water or ...
