Question: What happened to the lost colony of Roanoke?
Position‹5 of 5: The lost colony of Roanoke disappeared due to a zombie plague
Argument: The colony of Roanoke suffered from a zombie plague

. It may offer an explanation as to the swift disappearance of all the colonists, and the lack of evidence tied to a skirmish with local Native Americans. Also, as Roanoke was an island, it could explain why the infection was contained to just this locale.

The argument

The colonists of Roanoke Island could have been the victims of a remarkable phenomenon, a zombie plague. It may offer an explanation as to the swift disappearance of all the colonists, and the lack of evidence tied to a skirmish with local Native Americans. Also, as Roanoke was an island, it could explain why the infection was contained to just this locale.

Premises

[P1]Proponents of this speculative theory suggest a "zombie plague" could account for the Roanoke colonists' swift and total disappearance and the absence of evidence of any skirmish with local Native Americans. [P2] They add that Roanoke's status as an island would explain how such an outbreak remained contained to that single locale. [C] On this unverified account, the lost colony of Roanoke disappeared because of a zombie plague.

Counter-arguments

Zombies are not real, rendering this theory impossible. Moreover, it is much more likely that the colonists resorted to home-grown cannibalism, rather than suffering from a zombie plague. John White returned to England in the first place because the colonists were starving, and Roanoke Island was experiencing the worst drought in 800 years. A Harvard archaeologist, Lawrence Stager, allegedly found indications of cannibalism on the site, perhaps revealing the settlers’ desperation.

Rejecting the premises

[Rejecting P1] The premise appeals to an agent for which no evidence of any kind exists, and an unexplained disappearance is not explained by proposing a cause never observed anywhere; the absence of signs of a skirmish is equally consistent with the colonists having left, which is what the "CROATOAN" carving found at the site indicates. [Rejecting P2] Containment on an island is a prediction the theory makes rather than evidence it has met, and the documented circumstances — a colony already short of food, in a period of severe regional drought — supply an account that requires nothing unprecedented.
