Definition of "science" - 3a : knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method b: such knowledge or such a system of knowledge concerned with the physical world and its phenomena (Merriam-Webster Online)

Definition of "scientific method" - : principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses (Merriam-Webster Online)

Definition of "probable" - 1 : supported by evidence strong enough to establish presumption but not proof 2 : establishing a probability 3 : likely to be or become true or real (Merriam-Webster Online)

Definition of "hypothesis" - 2 : a tentative assumption made in order to draw out and test its logical or empirical consequences - hypothesis implies insufficient evidence to provide more than a tentative explanation <a hypothesis explaining the extinction of the dinosaurs>. theory implies a greater range of evidence and greater likelihood of truth <the theory of evolution>. law implies a statement of order and relation in nature that has been found to be invariable under the same conditions <the law of gravitation>.  (Merriam-Webster Online)

A hypothesis is an educated guess, based on observation. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven, but not proven to be true.

A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it.  [Hence the efforts to suppress evidences opposing evolution.]  Therefore, theories can be disproven.  Basically, if evidence accumulates to support a hypothesis, then the hypothesis can become accepted as a good explanation of a phenomenon. One definition of a theory is to say it's an accepted hypothesis.

A law generalizes a body of observations. At the time it is made, no exceptions have been found to a law. Scientific laws explain things, but they do not describe them. One way to tell a law and a theory apart is to ask if the description gives you a means to explain "why."

In normal usage, the word "evolution" often refers to both a fact and a theory.  Micro-evolution is the adaptations and changes within a species while macro-evolution is the addition of new traits or a transition to a new species.  Micro-evolution is a fact that is plainly observable throughout nature.  Macro-evolution is a theory that has never been observed in science.

Definition of “baraminology” - "created kinds” better describes the distinction between macro- and micro-evolution.  Whereas new “species” (by common definition) can sometimes develop through micro-evolution, the lines between “created kinds” cannot be crossed.  Genetic engineering (intelligent design) may attempt to induce such changes, but they cannot occur naturally.  As long as two creatures can hybridize with true fertilization, the two creatures are (i.e. descended from) the same kind. Also, if two creatures can hybridize with the same third creature, they are all members of the same kind. The hybridization criterion is a valid operational definition, which could in principle enable researchers to list all the kinds.  The Baraminology Study Group (BSG) has been instrumental in this area of research. The group is involved to further the development and research of this theoretical framework in creation biology within a forum of leading creation scientists in the relevant fields.

Definition of “design” - Through the study and analysis of a system's components, a design theorist is able to determine whether various natural structures are the product of chance, natural law, intelligent design, or some combination thereof. Such research is conducted by observing the types of information produced when intelligent agents act. Scientists then seek to find objects which have those same types of informational properties which we commonly know come from intelligence. Intelligent design has applied these scientific methods to detect design in irreducibly complex biological structures, the complex and specified information content in DNA, the life-sustaining physical architecture of the universe, and the geologically rapid origin of biological diversity in the fossil record during the Cambrian explosion.
