I've actually had that argument used on me.
At 3M years ago, I had a coworker who was a fervent creationist, and we used to have friendly knock-down, drag-outs not unlike some seen here on other subjects.
When you get to the point where fossils, or the light from distant galaxies, are "created in place" to fake humans out, you pretty much leave any realm where realistic debate is possible. Not to mention setting up some serious concerns about the mindset of a Creator who would do something like that. As if the Old Testament wasn't scary enough by itself...
