ID is religion lite, creationism with the serial numbers filed off in the hope of fooling school boards and legislators. It is a direct descendant of the creationism --> creation "science" --> "What do we do now?" problem as those previous attempts failed to fool the courts.
So, I guess you would classify the ancient Stoics as "creationist lite" for arguing that nature indicates an intelligent designer?
"Can any one in his senses imagine that this disposition of the stars, and this heaven so beautifully adorned, could ever have been formed by a fortuitous concourse of atoms? Or what other nature, being destitute of intellect and reason, could possibly have produced these effects, which not only required reason to bring them about, but the very character of which could not be understood and appreciated without the most strenuous exertions of well-directed reason?" (Cicero,
The Nature of the Gods, Book II, section XLIV)
