Do you think extraterrestrial life exists?

Our sun-system ends around 100.000 times as far away as the earth is to the sun. This x100.000 would be around the diameter of the Milky-Way. 25x from that away is our neighbour-galaxy, the Andromeda Galaxy. Our galaxy with all his neighbour galaxy's moves in a Galaxy cluster, our Galaxy cluster is called 'Virgo cluster', he has approximately 200.000 of all those galaxy's in itself. And these clusters move in so called 'Super Clusters'. And this is already the end of what we know about how big our universe is. The Super Cluster has thousands of thousands of galaxy's with all the stars and all the planets in it. Think about how much sand grains there are on a beach, in the Desert, in the whole world. And now think about the fact, that there are way more planets in the universe than sand grains on the earth. Who thinks there is no extraterrestrial life out there now?
