If you believe that aliens live on Mars, then what do they eat or how do they survive?
Surely, one of the most basic requirements for survival is liquid of some kind and food of some kind. Now, of course, their biology is going to be
radically different from ours, but unless they have evolved to sustain life from energy such as sunlight etc, then they will be 'growing' their food
just like we do. They are not necessarily carbon-based and so may not need water like we do but may need some other liquid found on Mars.
So, maybe we should be looking for liquid or food sources (apart from humans!) which we can use to add evidence of alien life forms on Mars.
On that subject then, I would like to suggest this.
Here is a MER microscopic imager picture of a RAT
It shows that under the surface of the rock is a void (since we are not looking at a ground-down/sanded-down area). This looks to me
as if there are species of fungus or lichen growing within the rock itself in voids beneath the surface. Possibly these are cultivated to provide
