People can only believe one or the other. You cannot believe that both were used to create the universe. Many people compare the universe with a watch. Both need somebody to make them work. As a watch needs a watchmaker, the universe needed a Creator. Chance is something that needs long random accidents to make it work which is totally impossible. It is like putting parts of an automobile into a tornado to see if a whole automobile could be produced. This we know is totally impossible because a tornado with its destructive power, tears things apart instead of putting them together.
"The most statistically improbable a thing is, the less can we believe that it just happened by blind chance. Superficially the obvious alternative to chance is an intelligent Designer." (Dr Richard Dawkins (Department of Zoology, Oxford University, UK),'The Necessity of Darwinism', New Scientist, vol. 94, 15 April 1982, p. 130).
The obvious design in creation extends for beyond earth's vicinity. For example, physical constants also reveal the Creator's distinct fingerprint. The precision accuracy of our universe as "user friendly" which means it appears to be designed for our well being. Truly the universe declares the glory of God. "The heavens declare the glory of God; and the firmament sheweth his handywork" (Psalm 19:1).
The strength of gravity, the mass of protons, the speed of light were created carefully for our survival. if these quantities were any different, universal instability and chaos would quickly result. The alternative, that these many balanced conditions arose by chance, has an extremely low probability.
To think the universe began with a "big bang" and evolved by chance over billions of years is very difficult to believe because from such an explosion, how did galaxies, stars, and planets eventually form?
The created universe, in contrast, suddenly appeared. The earth came first; the sun, moon, and stars were later formed on the fourth day of creation week. Over six unique days a vast quantity of directed energy was input to the universe from the Creator's infinite supply. Stars and galaxies suddenly existed in all their grand variety, much as we can see them today. "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" (Romans 1:20).
"The temptation to believe that the universe is the product of some sort of design, a manifestation of subtle aesthetic and mathematical judgment, is overwhelming. The belief that there is "something behind it all" is one that I personally share with, I suspect, a majority of physicists." (Paul Davies,'The Christian perspective of a scientist", New Scientist, 2 June 1983, p. 638).
