The main difference is that, a few centuries ago, the existing evidence showed that the earth-centric view was not tenable. Therefore, the theory was scrapped and another, new, heliocentric model -which fit - was adopted, tested , and found to be true. The trouble with ID is that, even though many of the theories are equally untenable, they keep trying to twist the logic to make them usable.

I can see that, but I think its primary statement is tenable or usable.
