I can't think of any scientist who disagrees with the idea that everything in the universe started from a single point. Maybe there's one out there. But if the universe started from a single point, why did it start? To me, because the universe started, it automatically means it has a purpose.

How did the unconscious become conscious? As smart as Darwin was, neither he nor anyone else can explain that one. But if you think life began through thunderstorms and sheer dumb luck then life is meaningless. There is no religion, no morality, no reason - you have boxed yourself in a corner because there is no point to anything.
