It could be that there is no reason for, or point to, our existence or the existence of the universe. It just is. To believe otherwise would suggest a planner with limitless power, intelligence and foresight. Such a planner would be obvious to every surface dwelling living creature, in the same way that diminutive little star we call our sun is visible to all such creatures.
Personally I don’t believe there is a grand plan or ultimate destination. Scientist are able to predict the length of time the universe will last before atrophy causes its disorderly end. Just cold dead burnt out stars and planets floating in space. Fortunately I won’t be around to see it or ask a god what the **** went wrong.
