Consciousness may evolve at a lower or higher state in the Universe. Too low; it falls apart or is killed to easily. Too high; the required space and time for the evolution is so great it requires a lot of space to find it.
Also, if a species evolves on one star system and ends there, it's not as likely to be located as one who travels. Hence, a conscious species that can star travel is just about the right place to find consciousness.
I could also talk about the idea of God and some physics.
Let's say for instance a lizard hasn't developed a tail that detaches when caught and that grows back. If that lizard has a higher consciousness, the time thinking wil just be a waste and besides the extra brain material will be dead weight, slowing it down, so you will not see these as much. If it has to develop wings before more consciousness, this will be so rare that likewise you will not see it as much.
Humans need limbs, heart, brain, machinery... The same goes for humans and their technology but there's one major breakthrough. If the humans can star travel they will be seen much more. Barely able to do it is where we would expect to see ourselves.
