and in the book, it was funny din that they did not do research to check for earth-only bacteria. the main character in the book was surmising that the martians were probably quite advanced in the sense that the martians eradicated bacteria from their planet already, and lacking knowledge about the nasties here, they fell victim.

aliw sa book when the main guy actually turned over the freaking-out priest to the aliens so that he (main guy) could be saved. hahahahaha.
