Life Discovered On Mars…Again! In NASA Surface Photos, Looks like Giant Snail.

I was looking at some videos and found one that is very fascinating.  This person discovered that some rocks have moved from their original positions and were in different positions latter in other photos.There are three different photos and the rock (life form) moves in each one, however on the third it is gone alltogether. Now I do not believe a rock is capable of this, therefore this object must have an outer shell and it lives safely inside much like a hermit crab or snail would. This object compared to the Spirit Rover would be about 1 foot tall. I googled the photos and they are real. Let me quote Spock from Star Trek, "If you eliminate the impossible, whatever remains, however improbable, must be the truth." SCW

The Navigation camera on days Sol 1833 to Sol 1843 was the source of the pictures. Here is a link to the Raw Images from the Spirit Rover on Mars: http://marsrovers.jpl.nasa.gov/gallery/all/spirit.html
