How about the theory that we are the way super-civilization spreads? If physical space travel is extremely expensive (as it should be, considering the distance), then may be it is better to send a signal that would trigger creation of life (in our case on Earth). Then when Earth civilization is advanced enough, it would be able to receive complete boot sequence and then fully advanced alien civilization would be replicated on Earth.
