Does bigfoot migrate?

The idea that bigfoot must be a creature that migrates can be linked to its possible predecessor, the giant ape Gigantopithecus whose fossilized remains were mostly found in the asian continent, particularly China. Bigfoot may have migrated along with the early humans and animals by way of the Bering land bridge that was known to connect Asia with North America during the ancient Pleistocene Ice Age. Again, these are just contentions because of the lack of documentary or physical evidence as to the existence of bigfoot.
