Na verdade, talvez se repita, mas a frase (matáfora) é bonita na mesma.

De facto, a água da terra é bastante antiga, sendo em parte anterior à formação do Sol:

«By reconstructing conditions in the disk of gas and dust in which the Solar System formed, scientists have concluded that the Earth and other planets must have inherited much of their water from the cloud of gas from which the Sun was born 4.6 billion years ago, instead of forming later. The authors say that such interstellar water would also be included in the formation of most other stellar systems, and perhaps of other Earth-like planets».
