Correct. That's why there must be more involved than just building
self-replicators and firing them off into the void. Some other failure
point(s) must exist. Not necessarily extinction events, but
alternative paths that avoid seeding the universe. Perhaps different
causes for each civilisation, as each develops differently. Or,
perhaps there is one insurmountable wall that we have not yet
encountered that applies to everyone.

Heh! :) That's like creationists saying that when God created the
world in six days, he also created fossils in order to test the faith
of believers. Occam would say that if all the *universe* looks natural
and undeveloped, then it probably is.

I lean more towards the 'something stops everybody' view. Perhaps they
are just having so much fun around Alpha Centauri that they can't be
bothered about elsewhere. :)
By the time we develop to their level of intelligence, we might think
the same way.
