Have we put life on Mars?

Unless the rovers that we sent to Mars were 100% Sterilized before they were launched, wouldn't they have carried with them lots of microorganisms, even ones that could eventually evolve into more advanced life forms?

That is a serious possibility, and scientists have done everything they can to avoid it, but undoubtedly some bacteria have survived the trip. Mars is still extremely hostile to bacteria, so ones that survive the trip are just as likely to die on the surface, and even if they survive in hibernation on the surface, there's no water and little chance of them reviving.

So basically, there is a small amount that survives but it isn't very likely to thrive on Mars.
