Is there life on Mars?
Currently, Mars is not suitable for advanced life forms, that being (in a very general sense) plants and animals. One of the main causes of the inability for life is the fact that Mars' atmosphere is about100 times thinnerthan the Earth's, and made up of mainlycarbon dioxide(the very gas that we rid our bodies of every time we breathe out).

It has only been in the past several years that scientists have found evidence of microbial life, and the search will continue until our rovers finally die.
