I will say that you have had the most reasonable easy to understand answer yet. If for no othe reason I want to go to heaven just so I may ask God
this question.
But mankind is destined to stay on earth, not heaven. John 3:13 "No man has entered heaven except He who came from heaven, that is, the Son of Man
who is in heaven." Earth will become a paradise after th 1000 year peaceful rule of Christ on earth at His second-coming. It will be an earthly
"Garden of Eden" for mankind.
