The earth is only ~8000 miles in diameter. The Milky Way alone is around 100,000 light years across, and is only one of ~3000 visible galaxies and an estimated 500 billion galaxies in the universe. It doesn’t seem surprising to me that there would be organic matter elsewhere in all of that. Incidentally, for those who say that they don’t believe there is a reason for all of this, and say they don’t believe in God, how can you truly believe that all of the vastness of the universe exists for no reason?
I agree. No way would God create all this and only produce life here.
