This has nothing to do with a "God of the gaps" agrument. If you claim it does please identify the "scientific" boundries of the "gap" you claim God is being plugged into.
ID proposes that natural selection of genetic variation is not a sufficient mechanism to explain the diversity of life and that God/the designer had to directly intervene to actually accomplish anything complex.
This is exactly a “god of the gaps” argument. The idea that where science (supposedly) cannot explain something - one must ‘fill the gap’ with supernatural forces.
Science depends upon predictable observable and measurable natural forces.
That is why ID isn’t science.
It proposes a supernatural mechanism.
