has anyone found anything alive on Mars..?

we have heavy weights like Author C. Clark, John Lear and many others that claim - this planet is in habited or was inhabited...
I look at earths antiquities, I see resemblance but still nothing I would say is 100%... of all the evidence I have looked at - well, the thought is a grand one... but the facts are... nothing Ive seen to date would suggest Mars is habitible from Nasa or any other source.
*this does not mean the moon does not have objects "other than nature made exists" the moon has reached the 60% probable zone... Mars is still vague and nothing but wishful thinking - unless you have something..
