The thing that most people take for granted is that science has irrefutable proof for what it claims......the hard fact remains....there is no proof and there never was.
You still don't understand the differences between proof and evidence.
Proof is a logic construct, usually presented as solution of mathematical equation, with some explanation to go with it. Proof falls under the realms of mathematics and theoretical science.
Evidence is observation and data that are detectable, verifiable, measurable, quantifiable and testable. Evidences are what determine the probability of theory to be scientific and factual.
It is evidence that make a theory "factual", not proof. Scientific theory required evidences not mathematical proofs.
Scientific theory explained the fact of nature, through observation, i.e. testing or evidences.
Evolution is not theoretical, it is experimental biology, where conclusion are based on evidences, not on proof.
And lastly, there are no such thing as "irrefutable" proof in science.
Nothing in science is irrefutable. Science only deal with what is probable and what isn't probable, and this is determined by evidences; the number of empirical evidences will -
(A) either be "false", therefore "refuted" it,
(B) or be "true", hence "verified" and "validated",
(C) ...and the 3rd probability that if it is untestable (no evidences whatsoever), it would be the same as (A), as "false" and "refuted".
Both creationism and Intelligent Design fall under C, as they are unfalsifiable and unscientific, because God, Creator, Intelligent Designer or whatever you want to call it, is not testable.
The only thing that believe in irrefutable is faith-based religion and religious dogma.
Jehovah's Witnesses, with it Watch Tower bible and theology relied on blind faith and manipulative propaganda, and you are perfect example of such wilful ignorance and deception.
