You have no idea whether Mars is a dead rock or not. Even if it now is, you have no idea whether it used to be alive or not.

So no, we shouldn't just dump random crap on Mars based on your ignorance.

Sure we do. It's a dead rock. All investigations have turned up nothing.

Scientists have given up on it being alive. They're reduced to looking for evidence of ancient life.
