I looked up Crick and panspermia. I concede the point, to my surprise. It seems odd to postulate directed panspermia by starfaring sapients over four billion years ago. It's so complex. Undirected spore-level panspermia is enough of a stretch already. Proving either would not be easy, but proving directed panspermia (in the crashing absence of alien signals or fossils) even harder.
