How many believe long ago that life existed on Mars, in somewhat comparison to Earth? We have seen images and read theories that the possibility of it. Was it possible long before Earth developed an atmosphere where life could survive, adapt and grow? I believe deep inside the surface, something does dwell surviving for it cannot on the surface, i.e. bacteria of some sort and possibly water of some type deep within. Something has to cause the atmosphere to have storms, along with orbital changes and rotation, unless it may be gas. Its just a theory I have.
