yes, but our civiliazation was already well established. it has
simple kept growing. if you had to start a new civilization on a new
planet, its likely that you would be too busy trying to survive for
the first few centuries to be bother with where you came from.

actually this brings up another point. there were several million
people on this planet when columbus discovered the america's, yet we
are still not to the point where we would have to send out more
colonizes. a colony ship that came from another planet would likely
have only a fraction of that. why would they want to expand to
another world so soon.

that is assuming that the new planet had been colonized either short
enough time that it was still using the old equipment, or that it had
had the time to develop its own. the odds are it would be in between.
