Your assumption
seems to be
that the costume could not have been created from a similar real kind of creature or accurate reports of seeing such.
The costume face is basically that of a gorilla, not like any reported bigfoot. The face of the thing in the freezer is also that of a gorilla, and not like any reported bigfoot.
I am not aware of any reports of bigfoot/sasquatch looking like a gorilla.
It is almost universally described as looking human. The universal excuse for not shooting it by those who had a chance to, is that it looked like a human and they couldn’t shoot at a human.
Besides, the costume face and the face in the freezer are not merely similar, but identical from the upper lip to the brow ridge.
What are you worried about, anyway?
This will be settled Friday at the press conference, won’t it?
BTW, none of these comparisons originated with me.
