Macroevolution, on the other hand, is an entirely different story. We'll have you guys believing we're all monkeys' uncles yet. Let's take a look at some terms. Creationists consider microevolution to be small changes within a species. The moth species stayed the same, but there were changes within that species.
Macroevolution is said to be the change from one species to another.
This naturally leads to discussions beyond species and into genus, family, etc., and ultimately leads to the question of whether we humans share a common ancestor with apes. So you got that right too. The problem is in your attempt to separate the two. Creationists have not come up with a reasonable explanation why evolution should stop at the boundary of a species, rather than include the process that changes one species to another over time. Fact is, there is no such reason.
