I think it is highly plausible that an alien microbe that infiltrates earth could cause a biological chain reaction that destroys life on earth. In the future, we (NASA) should avoid bringing back samples from outer space. In fact, I think it should be tested in the space center before bringing it here.
Right. And I'm sure they take great precautions. This sounds like a plot to a spooky movie.
I think we should be more careful to what be bring from Earth to space..... like, JasonX

When the astronauts from the Apollo 11 mission came back from the Moon, they had to spend time in de-contamination to make sure that they didn't carry any lunar microbes. NASA took this very seriously.
Personally, I am skeptical about an alien microbe wiping out all life on Earth. There are many problems it would have to face, not the least of which would be figuring out how to survive in a completely alien creature's gut.

I believe it was an infiltrating alien microbe that started life here.
