After learning how immensely complicated even a protein is, to say even less of a functioning cell, I’d say that discovering life out there would be a very literal miracle, and I use ‘literal’ literally.
Francis Crick, co-discover of DNA, realized that it couldn’t have “just happened” as it is so complex. So he came to believe in “pan sperma”. That aliens put the code of life into DNA and shot it out into space, wishing that it would land somewhere and be fruitful. Of course, I’m not sure how the aliens got life.
And many years ago it was discovered that DNA has a “shadow DNA” - so twice as much information as Crick thought.
