I don't see how. You've been on these threads long enough to know that evolution doesn't address the origin of life. It's possible life originated somewhere else, came here, and then evolved. We don't know enough to rule that out as a possibility, though there isn't any evidence to support it, yet.
How can life have evolved on earth, and then have evolved from outer space at the same time?
We don't know enough about abiogenesis yet to answer that. though we don't know enough to rule it out as a possibility, either.
The odds for THAT are, what? squared?
We don't know enough about the mechanism by which life originates to make that calculation.
If life transported to outer space, how could it survive, and live to return WITHOUT DNA?
Don't know yet. Certainly we don't know enough to rule out the possibility. It doesn't have anything to do with do with evolution, though.
