Gogs and Magogs

I'm quite interested in knowing about these mythical creatures.In Islam these are the creatures that will destroy most of humanity before Doomsday.Wad do u think these creatures that will "surge forth in numbers from the ground" are?

Some websites claim that these gogs are the people from western civilisations and Magogs are the western nations.I'm not too sure though.

Not creatures at all, but a group of people (Gog) from a certain nation (Magog)
