I was reading this Question earlier about how if water is getting lost into space and one of the answers said that (paraphrase) the Earth lost about enough water for the oceans to reduce by 12 cm, if the Earth lost that amount of water, could it make up for the loss by receiving Water from Space? I did research about this Source
Far from the Sun, where temperatures are low, water formed icy objects such as comets, while closer to the Sun water reacted with rocky materials to form hydrated minerals. It's thought that the mostly likely way that planet Earth inherited its water was from asteroids and comets crashing into it.
Is the Earth still receiving Water this way?
