Knowing there's flowing water means there's a better chance of life on Mars than if we knew there were no flowing water. And what does it mean if there's life - small-scale, bacterial-type - on Mars?
Well, I guess it means there's a better chance of life elsewhere. If two next-door planets have life, then the chances that an earth-sized planet in the Goldilocks zone round a star across the galaxy may have life as well. If it's similar to simple life on Earth, maybe there's a greater chance that the comet-dispersal theory of life is correct. In which case, maybe there's life around every cosmic corner. Maybe some of it would be complex, intelligent, brighter than us, fiercer than us, angrier than us. If we think it it old enough to cover the darkness of space between its home and here, we may have things to worry about.

And what does it tell us about the nature or presence of God?
It tells us this universe is wonderful and mysterious, with surprises and the potential for the generation of life. If you believe in God, it's proof - as if you needed it - that God is creative and endlessly imaginative - and has made a universe of wonder which is yet based on principles so utterly beautiful and simple. If you don't believe in God, stick with the first bit. If you don't believe in God, but you're a bit snarky and you don't think too hard, you may decide it disproves God. I still haven't been able to make that logical jump. There's people on Twitter who have but, like smug maths students, they haven't shown their working. And you know what happens if you don't show your working and you get the final answer wrong, don't you? No marks.
