I am proceeding from this observation: (1) right distance, (2) right condition... and then life. Life obviously is the goal for the preceeding two observable facts.
Why should there be a goal at all. Why not that life just occurs when the conditions are right. This earth may be the only planet with life or there may be millions of planets with life, obviously the universe is a pretty big place. To me life forms where the conditions are right, but there is no goal nor the earth is where it is so life can occur.
