Evolution is what happened AFTER life started, so no, a lack of life on other planets wouldn't say much about evolution. I think you meant to ask whether it would discredit abiogenesis being a natural rather than divine phenomenon.
And to that, the answer is maybe. We would expect that in the entire universe, some other planets would have conditions appropriate for something that behaves like life to appear and survive.
Of course the vast majority of planets would still not have life. You'd need the right combination of heavy elements, reactive-but-not-too-reactive atmosphere, shielding from radiation, etc. Even Mars, which has similar chemical and locational properties to Earth, doesn't have any life that we've been able to find in 20+ years of exploring it.
Still, I'd love to see creationists take up the burden of trying to prove a negative.
Please do explore every millimeter of every planet in the universe to prove that there's no life anywhere but Earth.
