I think it's the opposite. It would be much easier to believe in a god and think that there is something better in the afterlife. However, based on the scientific evidence so far that seems to be not the case. The fact that you believe in evolution but not for humans makes no sense to me except for thinking we are somehow special compared to other animals. We are not, we just have more intellectual abilities compared to other animals which places us as the dominant species on this planet.
