The more we explore and look out into the vastness of the universe the less science seems to understand. Despite all attempts to discover life on other planets and moons none has been found. Astronomers speculate that Goldilocks planets or planets that could support life are in other solar Systems.
Let’s assume that that is true. The nearest star is something like 4 light years away from us. At any achievable speed it would take 15 to 20 thousand years for a space craft to get there or to here. It will never happen despite what we see in si-fi movies.
For any real meaningful metric, life, all that matters is on this one grain of sand called earth in the vastness of the universe. We are the center of the universe! All that was created as far as can be seen or known was created so that we exist!
