“Russ, would you mind explaining how ID can be disproven?”
I’ll make a deal with you. First, you tell me how the random origin of the first living cell can be disproven, then I’ll tell you how ID can be disproven.
Disproving the random origin of the first living cell is a bit like disproving the idea that the entire text of the Gettysburg Address once appeared randomly on the Sahara desert due to random winds.
People who reject ID a priori don’t seem to understand what they are buying into.
You are omitting something very crucial: people reject ID as a scientific theory. ID may very well be the origin of life. It is, however, fundamentally unscientific. I'll offer a retort:
People that embrace ID as a scientific theory have no idea what science is. Or, perhaps, don't care.
