There will be moments in your life when you will dive into a deep deep thinking about the meaning of your life and life in general. These deep moments of trance will take place mostly after a tragedy in various forms. It is a byproduct of suffering.
You might start reading books like “Man’s search For Meaning” by Viktor E. Frankl and anticipating to find an answer…..an utopianistic place like Heaven, but you will not find one that exists.
You can search such a place but is such a place a reality to begin with?
There is no answer to a question “Is heaven a real place and does my life have a meaning?” and you can’t prove or disprove the existence of God with science.
