Creationism means Gawd did it.
That creatures were "shimmered" into being.
Intelligent Design means it could really have happened by ET. But some biological systems are so complicated, they couldn't have "evolved", they had to be created whole and "finished".
Of course, they both have equal data backing up their less than "scientific" theories.
This may be the only time you and I are almost on the same page rdean, but you have hit on other theories that belong in the ID category. Einstein's "God" was as he said: "I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with the fates and actions of human beings." In other words God was not necessarily a 'being' to Spinoza or Einstein, but was rather a sort of unseen cosmic intelligence because it was beyond reason, as they saw it, for such order as we see in the universe to have developed from chaotic happenstance.
Visitations from some super highly developed alien visitors from other worlds is another theory put forth by many.
For some Buddhists, the Creator is as Plato believed - the force of our own minds converts the cosmic intelligence or 'idea' into the recognizable components of our universe.
Aristotle's "God" was a concept derived from his understanding of physics. Because the universe as we know it is in perpetual motion, he reasoned that because everything is moved by something and movement is eternal, there must have been something that imparts motion without itself being moved - the unmoved mover.
So in the world of ID, it does not necessarily have to be a personal, identifiable God as beieved, perceived, and/or experienced by billions on the Earth, but does involve some form of intelligence guiding the process.
We could call the personal God concept the 'Big Boss' or even an unseen cosmic intelligence could fill that role.
There indeed may have been a 'big bang' but something had to pack the explosives and light the fuse.
Or there's the vacuum cleaner theory. If you put all the parts of a vacuum cleaner in a sack and shook the sack, given unlimited resources of energy and time, at some point all those parts would come together as a working vacuum cleaner. Thus all the components of the universe have always existed and came together in the form as we know it at this time.
Plato, Aristotle, Einstein et al rejected that apart from the "Big Boss" though. They all thought something would be necessary to shake the sack.
All this to say is that ID has every bit as much place in our education as does Darwin's theory of evolution. It is the only way to stretch our imagination and learning capacity to seek what we don't yet know.
