We know that the creation of a human body is more sophisticated than the creation of the body of any animal. The human brain is the most sophisticated and complex organ in a human. This shows the great power of the Creator. But we have to notice that the creation of the rest of the universe, such as the Earth, the sky, the sun, the moon, and all the galaxies, is more complex by far than the creation of human beings.
Everything God has created in the entire universe is acknowledgement of the existence of the Creator. Unfortunately, most of mankind denies God's existence and His creations. All these physical entities like stone, sand, trees, mountains, etc., are without brains. The birds, fish, and animals worship God in their own different ways. They worship God continuously with their limited brain capabilities, as God described. Then why do not all human beings, with their high level of brainpower, worship God? The human being has the most intellectual brain God ever made, way above all the sensations of plants and bacteria. Despite all that, most humans do not recognize God or worship Him the way He should be adored and worshipped.
