I see intelligent design and creationism as synonymous whenever intelligent design implies a supernatural designer and creator, unless you think that the designer and creator were different agents.
I think that natural design, and the intelligence it embodies, is obvious and observable. It is what the practice of science is intended to help us explore and understand. While the "designer" and the "designer's intent",
if such exists, is not obvious and directly observable. And is not a question that the scientific process can help us determine and understand. At least not so far. So I think as we learn about the design, but not about the possible designer, we need to remain humble and open-minded. Because we are still a very long way from understanding the whole of this mystery.
Biblical creationism asserted as a reality is a lie. It is a deliberate lie being told and bought into by people who want to assert their religious texts and the mythology within it as an absolute and unquestionable authority on truth, that they can then use to dominate and subjugate everyone else. It should be rejected and exposed for exactly the fraud that it is. But as we do so, we should remember that natural design, and the intelligence that it embodies,
is our reality. And if this does imply some sort of "designer", and the possibility of intent, then so be it. Because for us to deny this simply because we don't like some religious liars using it to their advantage, would make us just as willfully dishonest as they are.
