Yes, that is the least scary. If species like us are stuck in our own solar system, we're eventually doomed. If we're not, it would only take a few million years to colonize the galaxy. If two non-stuck colonizing species exist at the same time they have to arise within a few million years of each other, in a galaxy thirteen billion years old.
Frankly, us being the only/first sapient species is by far the most optimistic possibility.
- wing-_-nuts 5y agoBasically, for us to colonize another star system I think we have to be a space native species that no longer needs to. I think by the time we colonize anything beyond alpha centuri, there are more of humanity living on o'neil cylinders than on any planet, and the people living on planet are the ones that desire to live somewhere 'wild'
