The material elements means earth, water, air, fire. A scientist means, or a craftsman means he can utilize the ingredients in such a way. Just like this temple. It is a composition of earth, water, and fire. Tejo-vāri-mṛd vinimayaḥ. Tejo means fire, and vāri means water, and mṛt means earth. So what is this building? It is... You have collected earth, and shaped it into a brick, and then put it with water, and then put into the fire—it becomes brick. Then you smash it, powder it, it becomes mortar. Then you set up. In this way... The, originally, tejo-vāri-mṛt. Fire, water, and earth. So the fire, water, earth, has not made this nice temple. It is the person, the brain, the engineer, the architect—they have made.
So this is a wrong idea, that matter is doing independently. That is not possible. Therefore it is clearly said in the Bhagavad-gītā, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). Matter does not work. The Supreme Personality of Godhead, by His different energies, He is working. That is Kṛṣṇa. You have to understand like that.
