True, I suppose. "Is Bigfoot real"? To answer that, one must define "Bigfoot".
To some, it must be a new species. Period. Otherwise, even if you drag a huge, hairy creature out of the woods and its DNA is determined to be homo sapien, it is not "Bigfoot". As absolute proof of that, I point out the Zana affair. All the people who knew her referred to her as an almas. Today, after DNA analysis, there are people willing to argue until the end of time that Zana was not an almas, even though there is absolutely no reason why a homo sapien cannot also be an almas, or vice versa.
