Comets do fall from time to time, and Earth collects 5000 tons of debri from space each year. So I imagine Earth does gain a few tons of water from time to time.

That is a lot more than I would have guessed. I had thought that we were very slowly leaking precious resources by sending rockets into space, but I guess we're actually still gaining resources on average.

(At least, I don't think we're sending 5000 tons beyond the atmosphere every year).
