Evolving from a primitive life form to an advanced intellegent specie would take hundreds of thousands, if not millons, of years. Once reaching intellegent status they would have to exploit whatever energy sources they could find to develp a civilization. All the while, they would be faced with a host of natural and self-caused disasters, including mega volcanic eruptions and astroid strikes. At one time, modern humans almost disappeared from the face of the earth due to the impacts of a mega volcanic eruption. All these obsticles, challenges and limitations would make it difficult for such intellegent life to move beyond their home planet.

from what i understand of the earths history, our planet as it is , is infantile compared to much of the universe, due to our moon which was once a planet colliding with out planet, any sign of life on either planet would have been completely gone, though a planet broke off of its orbit probably wouldnt be able to, and if it was for the moon we wouldnt have day and night or the tilt of the world the way we do, which may have contribute to life since light is evenly dispersed, but back to the point we are techically very new compared to other planets which that were not hit with other planets
