No, THAT doesn't make them superstitious or mystical.
They state very plainly where things came from, where they are going, and why.
And it is sometimes right about them too.
As such they form the perfect foundation upon which science may apprehend the details behind it all, and science does so daily, no thanks to the superstitions of Darwinian philosophies.
Your basis for this...opinion?
A preponderance of physical evidence that concurs with what is written in the biblical texts, which evidence is chiefly found in the ubiquitous presence of organized matter that performs specific functions on both microscopic and macroscopic levels and is roundly supported by archaeology. Not to mention the fact that no part of the biblical texts invites dismissal on the face of it.
It stands to reason that an almighty Creator, who takes a keen interest in His creation, would provide a means whereby He could make known His actions and intentions toward the one creature capable of science. That means is called "language." Nothing mystical, superstitious, unclear, or even unscientific about it. Science cannot happen with out language, and language cannot happen without intelligent design.
