Sending human beings to explore Mars poses a high risk of biological contamination that would prevent accurate identification of alien life.
“My fear, or anxiety, or taxpayer arms akimbotic-ness is, if you send people, you're going to contaminate it. You're going to make a mess. And then, will you be able to determine, distinguish between what may have grown the leopard spot patterns or what humans brought by accident?”
