Pretend for one moment that God is real and He made you and He knew you before you were born. Then after death, you will spend eternity with Him. Therefore,this life is only a whisp of smoke compared to eternity. Earthly tragedies are MUCH more tragic to Athiests because they think this world is all there is.
Adam and Eve ate the forbidden fruit in the garden of Eden. Now humanity has to live with the consequence of that decision until the end. God doesn't intervene in global tragedies because Adam made our decision in the Garden of Eden. Some persons would ask, " How can that be FAIR for Adam & Eve's sin to fall on US? The answer to that is in the book of Romans....
"Therefore, as through one man's offence (Adam), JUDGEMENT came to all men resulting in condemnation, even so through one Man's righteous act (Jesus), the free gift came to all men resulting in justification of life." Romans 5,18. (parentheses added).
Do you see it is NOT fair what Adam did to us... and it
is equally not fair what Jesus did for us also! But the two added together make sense and fairness is restored!
A non-believer only sees the physical world, and doesn't perceive any spiritual reality. With that kind of world-view it is understandable to conclude "There is no God." or "God is indifferent." Read the book of Romans and most of your questions will be answered. It is only about 12 pages long.
Also, the book of Revelation shows we are living in the LAST DAYS where earthquakes and other bad things "Must come to pass." as predicted 2000 years ago in the bible.
