So this raises the questions related to the "amount" of gravity and the "development" of life... into creatures with the body types-features to interact and modify their environment... develop tools and so forth... and an environment with "raw materials" for tool making and so forth.
It raises a humungous number of related issues....which is one of the reasons I support the 'rare Earth' hypothesis. The number of inter-related steps required for us to become a space faring civilisation is huge. People have this crazy idea that all one needs is a planet in the Goldilocks zone with some water and the right elements...and the Klingons emerge.
Our aliens need an atmosphere with oxygen, because that is required for fire...one of the most basic tools for civilisation. An advanced technological civilisation would never arise on Titan, because though there are lakes of hydrocarbons there is nothing to cause oxidation and thus burning. If there was oxygen on Titan you could ignite the entire planet ( which would be rather fun to watch ).
Aliens would need some equivalent of trees, or they'd never get to build houses or ships. They'd need vast periods in which hydrocarbons were laid down, to create some alien equivalent of coal or oil. They'd need an atmosphere thick enough for flight, but not so thick that it behaved like a liquid and made movement difficult.
And so on. We are here as the end result of thousands, possibly millions, of factors being just right. Personally I doubt there's any aliens within 10,000 light years...or even in the entire galaxy.
