Aliens leave message on creek bed.

If you cannot understand or explain something the best thing to do is just make something up.  Driving up to a trail head yesterday Kadizzle and The Commander came across a massive rock display.  Creek rocks were carefully stacked in every direction.  Who did this, whey did they do it, and what does it mean.  It is all very simple.  The rocks are a digital message from aliens.  Each rock is a series of bits and bites just like computer code.  All you have to do is figure out the code and you know exactly what the aliens are saying. There are a few minor problems.  Do aliens read from left to right, top to bottom, or from north to south.  After a great deal of puzzling Kadizzle was able to figure out the code. This is what the aliens said. " Earthlings you idiots, you have enough to eat, all the energy you need, and all the resources to live very comfortable happy lives if you would just share.  Instead you fight and kill each other for the most silly reasons, and squander your planet.  We don't wish to visit any more, it is depressing".
