Another consideration is that one may want the flag or symbol to have relatively direct temporal associations (one way or the other), since longtermism concerns time. It seems to me that Ryan’s suggestion doesn’t have that; at least not very directly—it’s more about us being small relative to the vastness of the universe, which is something spatial rather than temporal.
Greg’s suggestion has stronger and more direct temporal associations, I’d say.
Generally, it’s of course not very straightforward to represent something temporal visually.
