Virtual archaeologists do not get tired of looking for new evidence that Mars is not completely lifeless planet. And even if there are no Martians on it, the aliens have long chosen it for their numerous bases or temporary stations, they prove.
Another find of ufologists is this "modest picture" taken by the NASA orbiter. With a strong increase, according to tireless space explorers, you can quite see something like a huge hole, which is nothing other than the entrance to the Martian base of aliens, whose presence on the Red Planet has been proven more than a dozen times.
The fact that it may well be just a cave or some kind of recess on the surface does not suit ufologists in any way. They have serious arguments for this. First, they write, the hole is very similar to the entrance to an underground labyrinth located in the North Polar Layer. Secondly, this hole is not observed at this very place on the Google Maps images, which proves that the photo was retouched by Google employees. And if this is so, it means that they also noticed this suspicious hole and "removed" it.
Interestingly, such findings of ufologists somehow help us, earthlings, to explore Mars and understand what it is? Or just interfere with scientists?..
