If there was no creator, then consider for a moment what it would take for life on earth to have begun by chance. For life to have come about, somehow the right chemicals would have had to come precisely together in the right quantities, under the right pressure and temperature with the right amount of other controlling factors maintained over the correct amount of time.
Moreover, these precise conditions would have had to be repeated millions of times.
But how likely is it for even one such event to take place by chance? According to leading mathematicians and scientists (evolutionists and creationists alike), the probability of the right atoms and molecules falling into place to form just one simple protein molecule is 1 in 10 to the 113th power (that’s 1 followed by 113 zeros). This number is larger than the total estimated number of atoms in the entire universe.
Mathematicians dismiss anything taking place that has a probability of less than 1 in 10 to the 50th power much less anything happening in 1 in 10 to the 113th. But far more than one simple protein is needed for life. Some 2000 different proteins are needed just for a cell to maintain its life, and the chance that all of them will occur at random is 1 in 10 to the 40,000th power.
To the logical mind these calculations wipe out the idea entirely that life originated spontaneously on the earth. All evidence points to order and design throughout the earth and indeed the whole universe. From the study of the tiniest atom to the giant nebulas, one can see logic and order in everything that is taking place. It has already been established that this order is governed by mathematical and scientific laws that are constant and maintained.
If, then, we have a universe that is governed by laws (as everyone admits), we can perceive that there had to be an intelligent lawmaker who formulated and established these laws. And that is just what Scripture declares, “What may be known of God is manifest in them, for God has shown it to them. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead” (Romans 1:19-20 Romans 1:19-20  Because that which may be known of God is manifest in them; for God has showed it to them.
 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
American King James Version×).
Design and order are not only seen in the patterns of the universe but in the workings of living things around us. Take for example the marvels of the human body. How, for example, does the pancreas maintain the correct level of sugar in the blood? Without it we would all fall into a diabetic coma and die. How about the heart that beats for over 70 or 80 years without fail? Or the kidneys that filter poison from our blood, taking out the bad and leaving the good? Also, the eye and ear show such intricate design and complexity that modern medicine cannot fully explain it.
Who showed the womb how to receive a tiny egg and help turn it into a complex organism with millions of specialized cells with different functions?
Who designed the animal and plant worlds with their hosts of beautifully interdependent workings? Who created bird and animal migrations and chose which species would migrate and which wouldn’t? Who built photosynthesis into plants so that almost all living things can ultimately receive their life-giving energy from the sun?
There is no God? Only a fool would say so.
