Life may not be that unusual but it might be mostly just goo: little extremophile type bacteria and maybe very tiny creepy crawlies living in deep seas, underground, in liquid mantles in ice moons, etc.
But to get stuff even as sophisticated as frogs and bunnies, let alone something that can try space flight, requires a place that is all of: big, stable, with abundant energy, with high enough metallicity, and in an environment well shielded from flares and impacts.
There may not be a lot of places like this.
"In 1995, geologists Roger Buick, Davis Des Marais, and Andrew Knoll reviewed the apparent lack of major biological, geological, and climatic events during the Mesoproterozoic era 1.6 to 1 billion years ago (Ga), and, thus, described it as "the dullest time in Earth's history"
By comparison, Earth may be barely habitable. It is amusing to think that we may be living on the galactic equivalent of Australia.
Perhaps the upside is that our gravity well is low enough to make routine spaceflight possible.
