So are you all saying that its just another rock formation and that the supposed legs are created by the image being blown up? Really because that doesn't explain why its on the cave wall or why it has that circular pattern minus the supposed legs. I like the explanation you've created though, just wish you had more than just a JPEG answer which seems like a fall back standard now a days.
Actually it DOES explain why its on a cave wall. Two major things occur when people look at rocks etc. First, there's the propensity for people to find patterns where they dont exist.. its an evolutionary thing. Humans have evolved to look for recognizable patterns, thats why we ended up with the constellations. The second, as Mick mentioned, are the issues with digital photos being enhanced. You can only "enhance and zoom" so much before you start losing fidelity and clarity. Pixels act just like the little dots in news print.. they're an optical illusion.
With news print, the dots are so close together that the human eye cant separate them any longer.. UNTIL you get super super close, or you magnify them. Digital photography works EXACTLY the same way. These are the artifacts that Mick is talking about. When the photo is enlarged beyond the resolution than the picture was taken in (because of the limitations of the camera) the pixels begin to break down. Our minds, being what they are, still try to find familiar shapes to latch on to, because thats what theyve evolved to do. You get the same effect when you look at clouds. The clouds arent ACTUALLY shaped like elephants or cars or faces, but our minds SEE them that way because its has a resemblance.
All of us here WANT there to be life on other planets.. its the nerd in us all.. but we're going to be scientific about it. If there's a more reasonable explanation, then thats what you're going to see us go with.. if there's NOT a more reasonable explanation and there's no evidence to support that its life (as there is no such evidence now) then we're going to say "Hey thats neat, lets hope we get some higher resolution shots of it so we can see what it is." If those high res shots come back and its an animal frozen in the rocks.. guess what? we're gonna say "holy SHIT THERES AN ANIMAL FROZEN IN THE ROCK.. FREAKIN SWEET MAN!!!!"
