I've definitely had this thought before. Humans are like a long shot bet. It comes at the cost of the risk of a major extinction event but, if successful, could seed life across worlds directly. Imagine a hundred worlds all with life forms subject to evolution. Basically two ways of that life growing past its planet: 1) A lucky asteroid strike or other outside event 2) A form of creature that can build tools to get out of the planet Only #2 would have an inbuilt strategy for galactic survival.
