Thesis for life in space

The question of whether the planet Mars had ever supported life remains unanswered to this day. It's frequently compared to earth, even sometimes being called "The Second Earth". Different missions have done samples and tests resulting in evidence that suggested mars having life on it. However they do not have quite enough evidence to fully back these statements up. In the near future, one could expect to see NASA launching plenty more missions to figure out the planets climate and geological features and how they change over time. In addition, in the coming years people will even be able to go to Mars, but to live. Foundations are raising money to put these projects into action and to finally somewhat conclude the question of life on Mars.
