Panspermia
I'd say it is none of the above. It is another possibility for how life arose on earth. It is interesting as an idea in it's own right but it's going to be tough to find any evidence in the short term. (ignoring what's on Mars as of now).
It would be ID if someone said that intelligence brought life to earth. It would be creationist is someone said that God created life elsewhere (the garden of Eden is on another planet? ). Otherwise it is just an idea.

Common sense isn't

Surviving
I believe you are incorrect. I think some spores survived on the surface of the moon and there is significant concern about "seeding" Mars and other places which would mess up exobiology studies.

Compounds from space
I don't get all the fuss here. To suggest that fully formed DNA would come from space is reaching way beyound what evidence we have.
And, of course, abiogenesis made use of compounds from space. Everything here came from space! Geez.
It is interesting that the early earth could have gathered up a number of useful small molecules after they had formed in space. This allows for very large quantities of them very early in earth's history. Beyond that I don't think it is anything to get very excited about.
What would be interesting is what would the density of the sugars (for example) be, would they be caputured or be pushed away when the solar wind fired up? If they form in space is it necessary they came from there? Why can't they have formed here as well?
