If they find some sort of life on Mars, microbial or whatever when they eventually go there, then I'll agree that there must be loads of life but if they don't find anything on Mars, then I reckon we're very very special indeed and it's possible no other life exists.

Except the universe is much bigger than that so you can't use statistics to make such a claim. 1 in 13 planets out of how many?
