Presuppositionalism starts with the self attesting God of scripture, and the "presupposition" that His Word is 100 percent true, infallible, and the ultimate standard by which all things are judged (at least, if you consider Van Til a presuppositionalist). Logic, science, morality, NONE of that makes sense, unless you start with the basis of God's infallible revelation to man, in which He communicated perfect knowledge to the created.
I am not sure why you are adding this definition to the term "self-attesting God of Scripture" since it is already contained in it.
Necessary. God is distinct from His revelation. You speak of God as ultimate reality as if it is some kind of ethereal concept. Its not. God is perfectly revealed in scripture, INCLUDING scientific truth and logical realities.
The perfect knowledge which is communicated is Scripture truth, not inductive science. "Creation science" as a presuppositional approach would require one to include the inductions of science within that "perfect knowledge."
Not at ALL. You completely misunderstand presuppositionalism. A presuppositional approach to science, is the same as a presuppositional approach to evangelism, parenting, or anything else. God said it. He said it clearly (doctrine of perspicuity). Therefore all inductive knowledge gained must be understood in the light of that which has been revealed.
Van Til taught all facts are interpreted by God. He did not teach everything which calls itself science is God-given.
Nor does Young Earth Creationism. They take plain, undeniable, visible truth, and interpret via the revealed truth of God. To say that a person cannot use logic and reason, is to deny what presuppositionalism itself demands; that God has given revelation to man, so that he might know truth.
Thus, "Creation science" or more rightly, "Young Earth Creationism," is by necessity presuppositional, as it starts with the Bible, God's Revelation, as its presupposition, and interprets all evidence by the light of that truth.
It is certainly presuppositional but it does not start with the Bible.
Certainly it does.
Creation science, at least the Young Earth version, does not "start with a certain view of science." It starts with the Bible. It then interprets all evidence in light of its presuppositions; God, and His revealed knowledge. It is, by definition, presuppositional (not to say that all who promote it use presuppositional argumentation).
Creation scientists start with the concern that their worldview is under attack and seek to defend that worldview by an appeal to evidence when their faith should be in the self-attesting God of Scripture. They invoke the authority of the Bible presuppositionally when they cannot prove their scientific position from evidence.
The way you are defining evidentialism, removes the possibility of presuppositialism as an apologetic at all! Apologetics itself is an "answer"; i.e., it is a response to an attack. Creation scientists (at least presuppositional ones like Ken Ham) don't start out "appealing to evidence." Ham shows the fallacy in the other's worldview, and appeals to the Bible. Saying "That rock formation got there by the flood" is not a rejection of Presuppositionalism...it is actually an EMBRACING of presuppositionalism. They are interpreting all of the data according to the Bible, without regard to the evidence.
Young earth creationism, at its core, is a presuppositional approach to origins. It is saying, "God said it, I believe it."
Ken Ham, if you are at all familiar with his work, is presuppositional. Heck, the guy quotes Van Til!
This proves nothing.
So, when a person uses the same argumentation that one of the fathers of modern presuppositionalism used, that doesn't make his arguments presuppositional?
Again, I wonder if you are actually familiar with Mr. Hams debates. Ham does not spend a lot of time trying to defend the logic of the resurrection, or demonstrating how animals could fit on the ark. He tears down the others worldview, using scripture. That's presuppositional.
