In the comic, aliens arrive with the intention of building such monuments with their highly advanced technology, including some sort of tractor beam to lift the heavy stones and another beam that can depict a pyramid. They are shocked to hear from [[Cueball]] that humans accomplished the same thing thousands of years earlier with such simple tools as ramps, and even in more than one location on Earth (Pyramids in {{w|Egyptian pyramids|Egypt}} and {{w|Mesoamerican pyramids|Mexico}}). Thus they proceed to suggest a stone circle to predict the solstice, but before they can finish this sentence [[Megan]] says this is like Stonehenge.

The joke of the strip is that, if aliens were interested in building such structures on earth, they'd be just as likely to show up today as thousands of years ago.  And if they offered to build pyramids today, humans would be very unimpressed, as we've had the technology to do so for quite some time. The notion that an advanced, spacefaring species would come all the way to Earth (or whatever other planets they visit) to build relatively simple stone structures seems dubious, when put that way.

Alternately, the aliens may have visited Earth before in the past and impressed the humans of the time with their advanced technology of pyramids and stone circles, leading them to expect the same technology to impress the humans again in the present day.  This is somewhat plausible: Stonehenge is estimated to have been built around 3100BC, while the pyramids were built 500-1000 years later.  Assuming both structures were indeed built by aliens in the past, the visitors would have returned to the Earth to find agricultural civilizations almost identical to the ones they encountered centuries prior.  The aliens could have then been led to believe that human technology, if almost entirely unchanged in the 500 years since they last visited, would not have advanced significantly in a few thousand years.  Indeed, the aliens were mostly correct in this assessment: technological advancement progressed at a crawl until the scientific revolution marked the emergence of modern science only a relatively short 600 years ago.  From this perspective, the aliens would seem to be correct in their assumption that human technology would not significantly improve such that they could not impress humanity with their technological wonders.  Unfortunately, the aliens have been caught off-guard by the exponential nature of technological advancement, in that advanced civilizations have the resources to advance even more rapidly.
