Here a series of God's signs in the system of the existence has been pointed to in brief:ِ

      ``Do the unbelievers not see that the skies and the earth were connected together as one mass, then We opened them?''

      Commentators have had a long discussion as to what the connection, and then the separation of the heavens and earth may mean. The most accepted view is that, the whole solar system has at first been one burning gaseous mass, and through its internal explosion it has been divided to huge parts, and then they have solidated to form the existing heavenly bodies, or the planets of the solar system that spin around themselves, and swim in their elliptical orbits.

      Another comment about it, is that; at the beginning, it did not rain, and the doors of the sky was closed. Then Allah opened it to rain down, and by that the earth began to grow its plant, and to produce its vegetation and fruit.

      The verses of Qurän are usually mainfold in meanings. Each verse may have a high meaning for a learned scholar, in spite of giving a lower meaning to a layman.

      Then reference is made to the importance of water:ِ

      ``And We have made everything alive of water.''

      Some commentators have understood this verse to mean that the main source of life is water, and that the first living creatures have been made in the oceans. Some other commentators have taken the water here to be the SPERMATOZOON which is the male reproductive cell, or gamete, able to fertilize a female ovum.
