Primacy belongs to the biblical texts not only because they speak plainly and offer no reason to question their authenticity,

How is this different than the texts of other religions? Please be specific.

but also because they largely concur with what is directly observable.

In what ways do they concur with what is directly observable?

The biblical texts are superior to all other texts because they have been supplied by the Intelligent Designer Himself in language that is neither esoteric nor fanciful.

You are assuming your conclusion. You cannot use the assumption that the biblical texts were "supplied by the Intelligent Designer Himself" in an argument attempting to show that the biblical texts were in fact "supplied by the Intelligent Designer Himself". You are appealing to a logical fallacy.

[Fester Chugabrew]

I take it as axiomatic that the biblical texts were authored by the Creator as a means to communicate the bigger picture of where all things come from and where they are headed. They are not mystical or esoteric texts, nor do they invite superstition. In fact they are quite the opposite, declaring these things in ordinary language even a child can understand. The biblical texts, like God Himself, are natural.

Contained the the command to fill the earth and subdue it is the injunction to undertake science. The texts themselves are sufficient evidence of God's existence and intentions, just as your own words testify to some extent not only of your existence but also your intentions. Am I assuming my conclusion when I conclude from your words that you exist and have intentions?

But you are not convinced the biblical texts were authored by anyone other than a collection of human authors, who themselves were inspired by nothing other than their own imaginations as they reacted to the physical world about them. Actually, those kinds of authors are the ones who fabricate Darwinism with all its esoteric spillage. You're not alone in this assessment. For personal reasons you've chosen to reject what the biblical texts say, and what they say of themselves.

Why did ordinary human authors arrive at a creation taking six days? An almighty God could just poof everything into existence in an instant. That makes for stronger drama, and is more consistent with an Almighty being. At any rate, the texts say of themselves they were authored by the Creator Himself. I'll take their word for it. It is reasonable enough, just like intelligent design is reasonable enough and not mystical or superstitious.
