Update: Below is the same face, flipped and mirrored side by side! This is what the aliens look like, screenshot credit UFOvni2012 of Youtube. Here we have before us the face of an ancient alien species.Their skull is very long which would indicate that they are highly intelligent.
Date of discovery: February 2014
Location of discovery: Mars
Someone at http://ufosightingz.blogspot.com discovered this face above so I thought I better confirm it there and check out the original NASA photo. It is there and then some. What I mean is I found a lot of faces smaller that this one, but it does confirm there were statues or monuments in this area long ago. Take a look at the other faces I found near it (below photos). Other faces I didn't include because of low detail.
I found something else that was overlooked. Some hieroglyphics were carved into one of the stones. I had to add a lot of light to the photo to even notice it, but it is there. There are two symbols, a straight line over a square. The photos of this are below, both before the light is added and after, then a close up of the symbols. Please have a look at the guys UFO site at the link above. It looks very informative. SCW
Update: These two people took the half face and flipped it over so we can see the whole face! Awesome idea!
