All I can say is if you believe Zubrin's claim that not a "shred of evidence exists for life on Mars" then you really must be naive. Mars has everything microbial life needs to survive. Just because Mars and Earth exchanged some material early in solar system history does not discount that life on Mars todasy could be dangerous to return to Earth. It has had millions of years to evolve to conditions there.

As far as the actual evidence goes? Here is a website full of it, not even mentioning the other evidecne from ALH 84001 and EETA 79001.

Should we just ignore this evidence because Dr. Zubrin says so?
