Thank you for your patience while walking these five steps with us. Let us think now: if intellect is required to build a house, then moreover intellect is required for the Earth (and everything on it) to come into existence. To live in the house for a long while it is necessary for someone to watch over that house, to do renovation, to replace something etc. To sustain the life on the Earth water and the air are the most necessary and the most consumable. If no one would take care of it constant cleansing those would soon become useless. Intellect is also required for it. The Earth does not exists just by itself. It exists in the Universe where everything is interconnected. Again we come to the conclusion that someone should manage it all..
