In theory they would be able to determine they were a much later addition. Then again, things like ancient Egypt lasted for thousands of years, so perhaps they will consider 2000 years a short amount of time.
That said, it does feel like the past few centuries (since the Industrial Revolution, but even moreso since the late 1800s/early 1900s) have seen incredible avancement in technology, unlike anything seen before. I mean electricity as we know it - the means to reliably generate and use it - have only been around for just over 200 years now.
