Castaway's Journal - Day 12-2

While taking a breather, I tried to figure out who those people were again, but to no avail.
If they're from the outside, like I am, it would seem strange that such a large group would not have information about leaving the island.
I can only come to the conclusion that they're remnants of the ancient civilization here, fighting for survival.
I can't fathom why or how they have guns, but it seems only natural that they must have created their weapons themselves.
That, or it's possible they're imitating things that have drifted onto shore for whatever reason.
