There is no evidence there was ever life on Mars. First of all, its mass is so small that there is practically no atmosphere. No atmosphere, no water.

Recently I was informed that abiogenesis is the process through which life first appeared on earth. That is, genesis of life from not life. Spontaneously, no initiating or controlling external intelligence involved or required.
