You're absolutely right. That's why I said its only a matter of time. Now that we've found traces of water, I truly think we will find traces of microbial life.

 

I'm not saying it's impossible, I'm not sure the conditions needed to begin life (at least on Earth) ever existed on Mars, and even if they did, there's also a high chance that the needed chemical reactions never happened.

 

To be honest I think the best bet for microbial life here in our own solar system is on Europa.  Mars is definitely a possibility like you said, but I think it is the first we are exploring because of proximity not because of odds.

edit: fixed spelling mistake, its just habit to add an 'e' to the end of "Europ".
