Problem with observing larger areas is that you're looking into the past.
Another problem with trying to observe an alien expansion wavefront is
that it propagates nearly with the speed of light and extinguishes
nonexpansive observers. The time window for observation is thus small
(assuming, we limit the term observation to sentients).
Anthropic effect is another explanation of Fermi's paradoxon. (You can't
observe if you're dead, and the lag between first hints and arrival of
pioneer wavefront is necessarily short, especially taking delayed
hatching into account).
