What I mean "telling us subtly", I mean through their Curiosity photos. Of course they are not going to say a peep about it verbally. At least not as yet!
Please go to these links and look at the hints nasa is giving us ! The "hints" are the subtle sea creature ghost - like bodies and mouths, The Images obviously have been degraded substantially to a sketchy like style but that seems to be a way nasa can slowly introduce us that they are in sea creature memorial lands! These were uploaded early this morning, I noticed them around 4:00 am, November 19th, 2015. I didn't see them last night.
I feel they must have committee meetings when they are going activate their subtle and sketchy revealings! You can see all of them with their thumbnails at:
Even if you look at todays Curiosity database in the two images released this morning (I think) in the Nav cams right and left cameras you can see slight hints of sea creature ghost like bodies and mouths as well. Even in todays releases in the hazard cams too! Of course it is all subtle and the images are highly degraded too look sketchy. The hazard cams have that bleached look but they do reveal sight hints of sea creature memorials!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
