Science is a method and we understand it very well. Science deals with objective reality. The fact that we can launch a rocket and have it meet up with and orbit another planet, much less land a rover on the surface more or less where we want to is proof that we have a handle on the scientific method. It is silly to argue that the earth is only thousands of years old. That flies in the face of objective reality. There are so many contradictions in Genesis that it can not be taken literally unless there is no such thing as an objective reality or God is an irrational being who wants to confuse us and torment us. I can’t believe either.
I agree, we do understand science very well, as it functions at this point in space and time. The problem is that there is no way to confirm that our assumptions about the past are true due to the fact that there's no way to actually truly verify the past. Yes, we can take note of things and make educated assumptions based upon those notes, but there is a certain limit to our understanding that is due to our inability to see time as a whole.
Now, you stated that there are contradictions in Genesis. Care to provide an example?
You’re confusing a hard, testable science like physics that enabled the moon landing, with a soft, speculative science like geology. Science that tries to reconstruct the past from looking at the present is never going to be as verifiable and reliable as science that studies things occurring currently.
Some worship Occam’s Razor over Divine Providence.
For science to place such faith in Carbon dating, it amazingly produces inaccurate results. Relative placement on a timeline might be strongly implied, but it is a poor attempt at absolute dating.
The scientific masses appear to huddle around their assumptions and acceptance of what they were told by teachers from early age and promoted by a worldly system of thinking. Real thinkers are humble enough to consider the Word of God and how our understanding might not yet be as sound as what He has provided.
