Well, almost everybody else considers bacteria life.
The scientific definition of life is something made up of a cell, meaning that viruses aren't considered life, but there is the argument to expand that definition to something along the lines of molecules that are capable of self-replication. If there is life on Mars (and thats a big IF), then it probably wouldn't resemble Earth Life (unless it was transported from one planet to another).
And bacteria are sentient in the simplest defintion of the word, they react to stimulus (which is another requirement for the scientific defintion of life).
