Yes, but earth carries vast amounts of ready to use surface water in this part of the spiral galaxy, so for local star travellers it's a cheap and quick stopover, instead of having to drill or laser/vaporise ice water deposits on the outer planets in our solar system.
Actually, it may be easier to go for that inert ice around Saturn etc, that is free of pollutants and organic materials.
Someone should warn them against colonising Africa though, they will never hear the end of it.
hehe - that made me lol.
