Not evidence life used to exist. Evidence there was water and habitable conditions. My apartment is kept in a condition such that a cat could live there but there's no cat. I have little doubt life exists elsewhere but this isn't proof of life. Just water. Still a big discovery.
I didn't say it was proof, it's evidence to support more evidence we will find on Mars itself. Evidence doesn't necessarily prove something, but it contributes. If you're trying to prove life used to exist, establishing it could live there is important.
