Replace 'first in their galaxy' with 'first in their own past light-cone' and you not only remove the assumption that travel between galaxies is difficult, but also explain the fact that we haven't observed any. If we assume they travel at near-light speeds and consume anything they can reach then any point from which they could be observed has already been consumed.
