Well, back when Adam and Eve roamed the land, Adam made a sign that said "Do not walk on the grass." Now of course, Eve wondered what 'grass' was and asked Adam what it was. Adam suddenly realized he had done wrong because there was no such thing as grass. So he and Eve prayed for 17 days, asking that God would create grass to grow around the sign. On the eighteenth day of prayer, God sent the angel Gabriel to scatter grass seeds around the sign. Then God brought rain upon Earth to let the grass grow. And the green grass grew all around all around, yes, the green grass grew all around.
