There is no other explanation other than "In the beginning God created..."

In the beginning God created the heaven and the earth.Genesis 1:1

The origin of any regulatory or interface system is, without exception, the product of an intelligent mind. It makes no scientific sense to explain the origination of any regulatory system as due to the “selective” powers evolutionists project onto nature. In fact, the mind behind the design of these systems must possess a thorough understanding of how every tissue functions and works together in perfect orchestration…equating to an astounding understanding. That mind is found in the Lord Jesus Christ, our infinite Creator. Our normal response to His marvelous creation should be the awe-inspired praise,… O LORD, how great are thy works! and thy thoughts are very deep. (Psalm 92:5). - Randy J. Guliuzza, P.E., M.D. (see more: http://www.icr.org/article/made-his-image-designed-control-systems/ )
