The idea that we are alone in the universe seems to me completely implausible and arrogant, considering the number of planets and stars that we know exist, it’s extremely unlikely that we are the only form of evolved life.
Time and space are finite in extent, but they don’t have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.
We are in danger of destroying ourselves by our greed and stupidity. We cannot remain looking inwards at ourselves on a small and increasingly polluted and overcrowded planet.
