If the planet is in the habitual zone for a given star with H2O then there is a biological chance some form of life exists. The evolutionary cycle for advances

If the planet is in the habitual zone for a given star with H2O then there is a biological chance some form of life exists. The evolutionary cycle for advances species development on the planet is the question. The human race did not evolve in a few million years. If there is a living advances species they could be very primitive compared to humans or much more advanced. There are so many variables that even science has not fully developed to come up with a plausible answer.
