there is an earth flag, and i see it being flown here and there by some advanced members of our species. seriously, this is a serious request. the flag i'm talking about exists, and simply has the earth photo (seen from space) over a navy blue background.
as for aliens from outer space needing flags for their planets, asteroids, etc., that's ok. of course, none of those are at this site, because they only play 3D chess (or maybe it's been updated to 4D by now).
do the developers even bother to read any of this?
