If we go up in space, the Earth is the only planet looks as the most beautiful object having different colors like some painter has painted it.
In my opinion, God has created the mankind as the best creation and created them to enjoy every moment of life on this beautiful Earth by extending good deeds turn the Earth into a real paradise.
God has blessed mankind with commonsense and wisdom to choose right and wrong. The law of requital "As you sow so shall you reap" will take care of us?"
Quran has commanded all mankind that after death we all will be resurrected and will be brought for justice and will be placed in heaven or hellfire where there will be no end of life.
