great chance of it actually, the universe is so vast no matter the advancements of our telescope tech etc. we will never be able to see the entirety of it and (I quote from space.com here) The vast majority of stars in our Milky Way galaxy host planets, many of which may be capable of supporting life as we know it, a new study suggests. Astronomers have detected eight new exoplanet candidates circling nearby red dwarf stars, which make up at least 75 percent of the galaxy's 100 billion or so stars. Also, the age of the earth is around 4.7 billion years old or so and, furthermore it has faced mass extinction about every 100 thousand years or so. With such declared we, as an intelligent race, really have not had much time to develop evolutionary speaking. Our sun has about a 10 billion year life span (which is half over), compare that to say a red dwarf which has more like 100s of billions of years to live, and based on that stars position in its host galaxy, if it dwells in a rather quiet part away from all major hazards threatening to blow the planet to bits, it goes without saying such a situation would be more stable and favorable for advanced life to evolve and grow intellectually and seeing as how the universe is nearly 14 billion years old, if they started evolving earlier in its life they could easily have billions of years head start of outsmarting us and as I always say if aliens came to visit we best surrender in a right hurry because obviously their technology surpasses ours if they got here in the first place over the distances we can scarcely comprehend. We'd be in deep do doo.
