So I have heard people sometimes say the reason for no aliens is that complex life requires so many coincidences it is just incredibly unlikely to indecently arise anywhere else in the universe. I think it is a bit arrogant to assume all life has to mimic life found here on Earth, so forgetting the goldilocks zone for a minute, you still need life to emerge from nothing over the course of billions of years. Then you need complex life to emerge from that, and eventually civilization. But you know what else you need?
Extinction.
No extinction means no fossil fuels means no industrial revolution means no spacefaring. If it wasn't for the dinosaurs, we would have nothing. Makes you wonder what we're here for.
I conclude that any advanced alien lifeform that gets to this stage will have to use a source of power not used so much on Earth. Hydro and Thermal seem unlikely, it's less portable and requires huge facilities, so it will probably have to something else. I imagine rivers of liquid gas, a space-faring civilization built upon lakes made up entirely of methane.
Edit:
It has been brought to my attention that fossil fuels are not in fact made up of ancient dead dinosaurs, and even if they were, we wouldn't need a meteor to make this happen. I just like Dinos 
I think there is a convincing argument to be made that one day we will create an army of self-replicating battle bots that will be able to do just that.
We could destroy the planet with grey goo by releasing tiny little nanomachines to clean up an oil spill, and even the universe if we released drones to harvest asteroids and use the raw materials to replicate themselves. In the event it all goes OK though, they could be directed to assemble something like a Dyson Sphere, and an AI could oversee the project to maintain order as a million things would inevitably fail on such a large scale. Not sure why we would want to do it at all, but an AI-robot workforce feels a lot more realistic than organising millions of humans.
But yeah though you try to do something like this you are for sure going to bump into the laws of physics at some point.
