That’s not what they’re saying.

It’s that a planet killer asteroid may have destroyed Mars’ atmosphere and turned it inhospitable to life. So if we do end up finding signs of even microbial life, we now have a fairly strong theory on why it didn’t survive.

If life existed and an asteroid impact killed it all, that would have a big impact on how we search for signs on the ground there. Plus knowing that life evolved on not just Earth is a HUGE discovery for the potential of other planets in other solar systems maybe having life.
