Our universe is very big. Roughly 90 billion light years in diameter and their billion if not trillions of galaxies in it. Each galaxy has billion and trillions of stars and Trillion Trillion planets are orbiting them all. If only 0.00001% of them are able to sustain life as we know it, then millions of Planets could harbor life. If so universe or even milky way should be teeming with alien spacecrafts but it’s not so. Why is it like that? In spite of that much probability where are all the alien?
