is there any case for Intelligent design in man made products

Because, when we look away from your posts, we see it in abundance.

Yes.
Funny AND correct.It's a gift.

And we do measure intelligence.

quote:

---

Intelligence has been defined in different ways, including the abilities, but not limited to, abstract thought, understanding, self-awareness, communication, reasoning, learning, having emotional knowledge, retaining, planning, and problem solving.

These are things that are observed and measured every day.

What exactly doesn't exist?
What is it that you are actually claiming doesn't exist?
Please be specific.

No. It would not be rational to infer an intelligent cause.If you are in a factory watching humans manufacture supercomputers, then you would know that supercomputers had an intelligent cause.
In fact, it would require a very poor grasp of reality to think otherwise.But if we look at a biological cell, we do not see any intelligent cause manufacturing it.
And to infer one would be baseless conjecture.{abe}
"...with artifical language" should have given you enough of a clue as to the flaw in your statement.
Can you name a single artificial object that occurs without an intelligent cause?Edited by Panda, : No reason given.Edited by Panda, : No reason given.

Correct.
It was a statement of fact. No suppositions are needed: we have a lot of evidence of intelligence in humans.
But if, for some absurd reason, you think that humans aren't intelligent, then I doubt that any evidence will convince you of such a self-evident fact. No, no. We know people are intelligent from testing and measuring.
It is not simply made up because it makes us feel better.So - are you honestly claiming that you do not know if humans are intelligent or not?
When you look at a human-made factory filled with humans building objects designed by humans - you just shrug and go "I do not know if any intelligence was involved."?

When scientists see a pocket-watch in the grass why do they not say "That grass was designed!"?
