I don't really see why it should be a problem.
It's a christmas special and it's not guaranteed that other planets would celebrate christmas on the same day that earth does

so it seems fitting that the special would be set on earth.
Not only that, but the trailer looks flipping amazing. I get goose-bumps every time I watch it (and I've seen it many times.)
Hopefully, series 2 will take us to some new alien environments, but for the christmas special I'm happy it's set on earth.
