Honestly I always doubted the likelihood of terrestrial sentient life forms, as water is needed for a planet to have life, and water is made from hydrogen and oxygen which are 2 of the most common elements in the universe, their for a planet with life would likely have a ocean and in a ocean more life would develop faster and superior to any on land.
