"Science begets knowledge, opinion ignorance.

To be clear, NASA is not declaring that it's discovered Martian life. Rather, its Perseverance rover has drilled a sample from a rock with attributes that could have come from ancient microbial activity, the agency announced Thursday.

Organics have been seen before, albeit not by Perseverance and at that locality.

But for all of this the rule is that if there are abiotic confounds it is the null hypothesis. Besides that it hints of thermal and redox processes that would support the abiotic origin:

The rock has other confusing features that muddy the picture of how it formed, Stack Morgan says. It is shot through with white veins of calcium sulfate. These veins are filled with millimeter-sized crystals of olivine, a mineral that forms from magma. The inclusion of both the spots and these volcanic features in the same rock is “a little bit mysterious,” Stack Morgan says, as they point to different origins.

What it does give us right here and now is a more heterogeneous environment with more possibilities for life.
