It is for sure, the elementary life does exist on Mars, like in many other places of our Solar System.
What do I mean with „elementary life“?
It is the most primitive form of life developing spontaneously directly from the universal quantum field (called also the universal matrix, the akasha, or the field of light) in form of the smallest possible quanta of the living matter. They are still smaller than the known nanobacteria, and even smaller than the nanobes, the smallest of which are just 20 nanometers in diameter. By using the traditional terminology, the universal quanta of the living matter can be probably most correctly named as the smallest possible protobionts.
These universal quanta of the living matter, emerging directly from the akasha field, are only about 5 nanometers in diameter (compare the Quantum Spectrum of Matter here above in menu of Naturics). They are surely not some independently living organisms. However, they are already the fundamental building blocks of such organisms. A living organism never disintegrates after death into smaller elements than such universal quanta of matter.
What are the best conditions for the existence of the universal quanta of life?
The universal quanta of the living matter emerge spontaneously under almost all conditions. However, they can exist permanently after that only under some advantageous conditions. Such a quantum needs a nanosized dust particle covered with a film of water-ice and a corresponding amount of solar (stellar) energy heating it to at least -30 °C. The simplest forms of the living-matter units are very probably like two-dimensional coverings of such „clammy“ dust nano-particles.
Where is an „incubator“ of the universal quanta of life on the Earth?
As already mentioned in this blog, the terrestrial „incubator“ of life is the tropopause around the whole globe. It should be noted that it plays also a role of a shield protecting the higher developed life on the Earth's surface against the dangerous cosmic radiation.
Where is a „life incubator“ on Mars?
The contemporary Mars is not a „healthy“ planet. It is a planetary cripple. What we can see today is just a remnant of the original Proto-Mars after a series of events that occurred 3,5 Mld years ago. The largest remaining fragment of the Proto-Mars collided finally with the Proto-Earth and created our Moon. This unlucky rest of this original proto-planet carries up to our times the traces of all its collisions. Unlike to the Earth, Mars does not posses a continuous magnetosphere. Mars' crustal magnetic field is relatively strong only in the southern hemisphere. Every once in a while, magnetic anomalies are found, where some magnetized substance is buried beneath the surface.
This asymmetry in magnetic field strengths is correlated with another odd ancient crustal feature on Mars. The northern hemisphere crust is thinner and lower than the southern hemisphere crust. Possible explanations for this dichotomy include a giant low-angle „impact“ in the northern hemisphere, the collision with Proto-Earth.
We can thus suppose that also the atmosphere of Mars should show similar bands or „islands“ of the conditions supporting the „incubation“ of life. We have to look for such places of the Mars surface and atmosphere, where the temperatures of about -30 °C coincide with some water vapour and dusty particles for some longer time. One of such possible „hot spots“ for life has been reported, for example, on an ancient Mars volcano.
