I read revelation 12 where it talked about a holy pregnant woman being targeted by the serpent. The serpent ended up not being able to reach her as she was in the wilderness.
So it is not that the serpent couldn't see where she was, nor did the serpent didn't knew. It couldn't reached her
Wilderness must be a place where people could make a living being 100% honest (and good and orderly or the variations of it, everything that's good). That place is a safe place but it is also known.
