I didn't realize people actually believed that.
I guess that's probably because they are taught that earth is a temporary "testing ground" and if they pass the test, the get a "Get to Heaven" card. If they fail, it's a "Go Straight to Hell" card.
So earth is really a bad place according to some religions.
According to the Bible though, the earth was made to be inhabited by fleshly creatures - both man and beast, and the trees and vegetation was to serves as a delight to their eyes, and taste-buds... and stomach.
Actually, the earth has what sustains us physically. The heavenly beings do not need to eat, breath oxygen, nor sleep. There is no milk and honey there, and no plants or animals - according to the Bible.
God did not even intend for man to go to heaven.
Some get that opportunity because they have been chosen for a special assignment - to be kings and priest with Christ - heirs of his
kingdom/government.
They will rule and serve millions who will live in paradise on earth with all the animals, and they will do no harm nor cause any ruin.
Why God Created The Earth.
We can enjoy our pet dog right here, when earth becomes a paradise.
