Obviously an intelligent cause has explanatory power
https://en.wikipedia.org/wiki/Explanatory_power
Explanatory power is the ability of a
hypothesis or
theory to effectively explain the subject matter it pertains to. The opposite of explanatory power is
explanatory impotence.
In the past, various criteria or measures for explanatory power have been proposed. In particular, one hypothesis, theory or explanation can be said to have more explanatory power than another about the same subject matter
- if more facts or observations are accounted for;
- if it changes more "surprising facts" into "a matter of course" (following Peirce);
- if more details of causal relations are provided, leading to a high accuracy and precision of the description;
- if it offers greater predictive power, i.e., if it offers more details about what we should expect to see, and what we should not;
- if it depends less on authorities and more on observations;
- if it makes fewer assumptions;
- if it is more falsifiable, i.e., more testable by observation or experiment (following Popper).
Emphasis mine. Let's go over them:
- The "intelligent cause" hypothesis offers no details of the causal relation. We have
no idea how an intelligence might have achieved this goal, and simply saying "he spoke it into existence" doesn't help at all.
- The "intelligent cause" hypothesis offers exactly
zero predictive power. There is no falsifiable prediction we can make based on "life is intelligently designed". Whereas we can make countless useful and falsifiable predictions based on the hypothesis that life evolved from a common ancestor (
for example)
- The "intelligent cause" hypothesis assumes a supernatural being. 'Nuff said.
- The "intelligent cause" hypothesis is
unfalsifiable, meaning that it is fundamentally useless, regardless of how well it explains the available evidence.
