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.
I think the human race doesn’t have a future if we don’t go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future.
