Here is the problem. If ID is without magic, then that means these beings came from somewhere. Now these beings may have had their own designer, and their designers may have had their own and so forth. Eventually their is a beginning. This beginning is where the leap of faith occurs for all believers of all of them, evo, creo, ID. A puddle of chemicals, the hand of god or just magically appearing. None can be proven yet fully. However one has come closest(IMO to both ID and Evolution).
At some time in a past so ancient that even God has lost track of it somewhere in the Multiverse (My Father has many mansions) life started or continued.
When God thought it useful He went to the nursery and brought plants, animals and people to the Garden He planted in Eden.
