Are we eternal beings in some way or just temporarily animated by the makeup of our organic chemistry? Did it begin at birth and does it end at death? These are timeless questions so far as mankind is concerned.
The reality is that we each have a mere century or less in which to carry out life's intended purpose. Why are we here on earth? Why is there opposition and suffering as well as happiness? Does anyone including atheists truly resolve themselves to believe that life has no eternal purpose.
Personal opinions have no effect on the actuality of truth. Theology must agree with science when the facts are indisputable. All science that we know in our limited capacity is a subset of the science that exists through out endless space.
