A key factor that we all must recognize is that the vast majority of scientists who believe in evolution are also atheists or agnostics. There are some who hold to some form of theistic evolution, and others who take a deistic view of God (God exists but is not involved in the world...everything proceeds along a natural course). There are some who genuinely and honestly look at the data and arrive at the conclusion that evolution betters fits with the data. Again, though, these represent an insignificant portion of scientists who advocate evolution. The vast majority of evolutionary scientists hold that life evolved entirely without ANY intervention of a higher Being. Evolution is by definition a naturalistic science.
For atheism to be true, there must be an alternate explanation for how the universe and life came into existence. Although beliefs in some form of evolution predated Charles Darwin, Darwin was the first to develop a plausible model for how evolution could have occurred - natural selection. Darwin once identified himself as a Christian, but later renounced the Christian faith and the existence of God as a result of some tragedies that took place in his life. Evolution was "invented" by an atheist. Darwin's goal was not to disprove God's existence, but that is one of the end results of the theory of evolution. Evolution is an enabler of atheism. Evolutionary scientists today likely would not admit that their goal is to give an alternate explanation of the origins of life, and thereby to give a foundation for atheism. However, according to the Bible, that is exactly why the theory of evolution exists.
The Bible tells us, "The fool says in his heart, 'There is no God'" (Psalm 14:1; 53:1). The Bible also proclaims that people are without excuse for not believing in a Creator God, "For since the creation of the world God's invisible qualities - His eternal power and divine nature - have been clearly seen, being understood from what has been made, so that men are without excuse" (Romans 1:20). According to the Bible, anyone who denies the existence of God is a fool. Why, then, are so many people, including some Christians, willing to accept that evolutionary scientists are unbiased interpreters of scientific data? According to the Bible, they are all fools! Foolishness does not imply a lack of intelligence. Most evolutionary scientists are brilliant intellectually. Foolishness indicates an inability to properly apply knowledge. Proverbs 1:7 tells us, "The fear of the LORD is the beginning of knowledge, but fools despise wisdom and discipline."
Evolutionary scientists mock Creation and/or Intelligent Design as unscientific and not worthy of scientific examination. In order for something to be considered a "science," they argue, it must be able to be observed and tested, it must be "naturalistic." Creation is by definition "supernatural." God, and the supernatural, cannot be observed or tested (so the argument goes), therefore Creation and/or Intelligent Design cannot be considered a science. As a result, all data is filtered through the preconceived, presupposed, and pre-accepted theory of evolution, without alternate explanations being considered.
However, the origin of the universe and the origin of life cannot be tested or observed. Both Creation and evolution are faith-based systems when they speak of origins. Neither can be tested because we cannot go back billions (or thousands) of years to observe the origin of the universe and life in the universe. Evolutionary scientists reject Creation on grounds that would logically force them to also reject evolution as a "scientific" explanation of origins. Evolution, at least in regards to origins, does not fit the definition of “science” any more than Creation does. Evolution is supposedly the only explanation of origins that can be tested; therefore, it is the only theory of origins that can be considered "scientific." This is foolishness! Scientists who advocate evolution are rejecting a plausible theory of origins without even honestly examining its merits, because it does not fit their illogically narrow definition of "science."
If Creation is true, then there is a Creator to Whom we are accountable. Evolution is an enabler for atheism. Evolution gives atheists a basis for explaining how life exists apart from a Creator God. Evolution denies the need for a God to be involved in the universe. Evolution is the “creation theory” for the “religion” of atheism. According to the Bible, the choice is clear. We can believe the Word of our omnipotent and omniscient God, or we can believe the illogically biased, "scientific" explanations of fools.
