By it's very nature, science is limited by the need to observe and to do so repeatedly. The dangers of extrapolation are well known. The problem with the scientific study of origins is that it can never produce more than a theory. One can never observe the process in the laboratory and one's understanding is always based upon extrapolations. In scientific terminology, it is "an ill posed problem." The scientist cannot, nor could they ever, observe all the data and repeat the experiment under controlled conditions.
Religion, by nature posits the existence of a god and is concerned with the relationship between that god and man. Christianity in particular (since that is where your attack appeared to be aimed) presupposes the existence of a God who transcends space and time and who has revealed Himself to mankind throughout history. Orthodox Christians believe that revelation was ultimately through the person of Jesus Christ and that our sovereign God was capable of preserving a sufficiently complete record of His revelation through the ages - in the form of what we today call the Bible. Orthodox Christians generally recognize that God prepared the writers of the Bible to faithfully and accurately record His intended communication. That communication was by nature designed to communicate with the original audience and because of the universal truth communicated is relevant and applicable to people of every time, including today. Again, most orthodox Christians agree that we need to let the author (God) speak for himself and guide our understanding of the record. This brings me to the creation accounts - Genesis 1, John 1, and Col 1:15-16. Looking at these together shows that the point is to present the pre-incarnate Christ as the Creator and Sustainer of all that exists today. The Bible also presents the created universe as evidence of God's power.
The problem comes in when scientists and Christians alike want to look at the Bible and read it like a submission to the Journal of Applied Physics or Nature or some other premier scientific journal. The text of the Bible makes it clear that God did not intend to author such a genre. God's intent was to present Himself to mankind as an orderly creator and sovereign over His creation, not to write a textbook of physics or molecular biology. In the end, those who accept Christ as Sovereign Lord and Creator and those who reject Him in favor of a totally naturalistic explanation do so by faith - either faith in One who gives us sufficient evidence if we care to look or faith solely in one's own reasoning. Either way, the decision is based on far more than "science."
