How about this:

or we have the probe search for a candidate planet.
But unless that planet (or moon) is relatively nearby, we'll be blindly seeding it, with no hope of seeing results for generations to come. It could be a desperation move to save an example of Earth life (maybe even us) if it becomes apparent that Earth is doomed. However, if that were the case, I think we'd be devoting our expertise and resources into surviving locally, sort of like in the movie Silent Running.
Or we could just broadcast our genome into space in the hope that ET would receive it and find a way to reconstitute humans, but we wouldn't know what use they might find for us.
