It make me think of Von neuman probe. If we can consider that a robot or something with connections similar to our neurons can be a living creature. Then maybe if something like Von Neuman probes existed it could have colonized the whole galaxy (actually it could be done in a few hundred millions years) then those probes, while each one have is own brain, could communicate with the other probes and even if two probes at two opposite sides of the galaxy couldn't communicate, they would still be connected. Then maybe this network could be consider as a living creature.
