Bigfoot is covered up because it's a collective of different species of hominid and describing just one of them as biological species would open a door for others. One of which would be relict hominid species of degenerated Neanderthal (Minnesota Iceman was one of these).

Modern humans evolved from African hominids in Levant. They also have lived in the same territory for ~50,000 years with Neanderthals.

Early humans evolved in Africa as omnivores.
European Neanderthals evolved in glacial Europe as strict carnivors and likely nocturnal pack predators.

Both Early humans and European Neanderthals competed in the same niche in a geographical land bridge between Eurasia and Africa: Mediterranean Levant (Syria, Israel, Palestine, Sinai etc.)

By virtue of being carnivorous nocturnal pack-hunting hominid, Neanderthals applied predatory pressure on Early Humans: they killed, consumed, abducted, raped. This predator-prey pressure turned Early Humans into Modern humans we are today (Them and Us was written by an amateur but it's supported by actual scientific evidence). Genetically modern humans had a bottleneck 50-75 thousands years ago down to 50 individuals.

So first Neanderthal hunted humans down to 50 specimens in Levant, then those 50 now Modern Humans turned tables and exterminated Neanderthals to near extinction.

That process probably worked in reverse too: Modern Humans applying pressure on Neanderthals forced them to adapt: adaptation #1 would be to flee into strongholds that weren't accessible to hairless humans: high-elevation, dark mountainous forests. Adaptation #2 would be mimicry (many animals, insects specifically, do that). Some Neanderthal might adapted to look human but kept oral lore of being distinct species in the past, the apex predator. Chosen People.

Now, most of the the species referred to as 'Bigfoot' have nothing to do with Neanderthal, but some do. And once their genes are examined - 'humans' that live in Israel would come under scrutiny.
