The first thing that comes to mind is their essence.
Oh well, lol thanks for clearing that right up. Seriously though, could you just explain what the difference is? When you give a really vague and non-definitive answer like "essence" you must know the next thing I'll be asking is "what do you mean by their essence?" That explanation adds nothing to my understanding of what you're talking about when you say "supernatural"...and it's pretty important to understand what you mean if I'm ever going to be able to understand what makes this answer so "efficient".
Or are you deliberately being vague at this point?
Once again, you don't have to have an explanation of an explanation in order to recognize it is the best explanation for something.
The best explanation for something is the one that correctly answers the question. There's really no other criteria.
When it comes to explanations like ID or creationism...I really have no idea if they could even be correct, because they leave so much of the question unanswered. Sadly, the people who trot those explanations out the most seem to care little for the questions they leave unanswered...and that should be a clue as to why those people are using those explanations in the first place. They aren't concerned about truth, accuracy, and being correct...they simply want people to agree so that others aren't challenging their deeply held religious beliefs.
If we received a signal broadcast from Alpha Centauri and we were able to convert it to an image and there appeared what looked like elaborate symbols and shapes and patterns and some sort of otherworldly language, we wouldn't have to know the method of transmission or even who transmitted it to explain such a signal as having been made by some intelligent efficient cause.
I'm sorry...what are you suggesting within this scenario? That we're receiving a "signal broadcast" from somewhere...and we don't know the method of transmission? Yet, in spite of this, we're converting the signal into symbols and shapes/patterns?
I'm not sure how you imagine this going down...but is that what you're suggesting? Or did you perhaps word it incorrectly?
Exhaustive knowledge of a thing is not a criteria anyone uses when assessing the merits of a hypothesis to offer an explanation of that thing.
You're correct...but ID doesn't offer any knowledge of a "thing" other than the mere guess that it's "intelligent". It's not even enough of an explanation for me to be able to determine if it has any merits with regard to reality.
A spider web, for example, can display all sorts of complexity...from the design, to the incredibly efficient material, and even from a mathematical standpoint...it's geometric patterns...yet I don't know anyone who would argue that spiders have any intelligence.
So even the "intelligent" part of "intelligent design" is nothing more than mere speculation. The entire hypothesis amounts to nothing more than "something did it"...and that's not a hypothesis that explains anything.
The notion that life on earth, with its attending diverseness, is the result of an intelligent agent back of it all does raise a lot of questions. The notion also provides answers to questions.
Well let's quit beating around the bush then...let's hear the "answers" it provides.
No hypothesis if adopted, will answer all the questions we may have.
No? I've always looked at explanations like "photosynthesis" as a pretty tidy answer to what was once a very difficult question.
Honestly, I thought I was being pretty generous above...because not only is the "intelligent" side of ID unclear...but so is the "design" side of it as well. You can call it an answer if you like...but it certainly isn't an explanation. It doesn't explain anything.
I don't know what you mean by "creative"...if you mean it's a creative answer, it really isn't. If you mean it's efficient with regards to "creation"...it isn't that either...it doesn't explain a single thing about the creative process, the creator, or how we can even tell that something is a "creation".
We could just as easily answer any of the questions that ID attempts to answer with the word "magic" and be on equal footing with this "hypothesis". How did the universe come to be? Magic. How did life first form? Magic.
Sure, that doesn't tell us anything about what magic is, how it works, or why we know it was magic...but hey, it sure is an efficient answer!
