there are probably a lot of reasons. But i'll give you one good one. Very FEW people actually stop and look backwards.

Let's suppose you are hiking down a trail in an area that you've never been before. You're excited by the vista ahead. So naturally you forge ahead. But you don't make frequent stops to look backwards - and see how the countryside (and landmarks) would appear when you are retracing your steps. Therefore ... how can you possibly expect yourself to find your way back home.

People with good map-reading skills, or GPS skills, or a good natural ability to spot and remember landmarks - do FIND their way back home.

Otherwise, getting lost is pretty easy, really!! :-)
