You say that only because you don't know what it is like to live a perfect life in perfect conditions, without sin and death...that was God's original purpose for man, to live on a paradise earth forever...
Further, God blessed them, and God said to them: “Be fruitful and become many, fill the earth and subdue it, and have in subjection the fish of the sea and the flying creatures of the heavens and every living creature that is moving on the earth.” Genesis 1:28
His purpose for mankind has not changed...it will be fulfilled...
"So my word that goes out of my mouth will be.
It will not return to me without results,
But it will certainly accomplish whatever is my delight,
And it will have sure success in what I send it to do." Isaiah 55:11
"Just a little while longer, and the wicked will be no more;
You will look at where they were,
And they will not be there.
But the meek will possess the earth,
And they will find exquisite delight in the abundance of peace." Psalm 37:10,11
