Evolution is not the only scientific theory out there. There are alternative scientific theories and very smart, non-relgious people who do not advocate or support evolution. (See http://blogs.scientificamerican.com/cross-check/dubitable-darwin-why-some-smart-nonreligious-people-doubt-the-theory-of-evolution/ as a starting point.)
I am not one to endorse criticism regarding evolution or Neo-Darwinism, but it is awfully two-dimensional to believe that the field is as polarized as Watchtowerism has portrayed the world. Science does not have their eggs in one evolutionary basket when it comes to explaining life's origins, neither does it find support in Creationism or some type of religious views. But the Jehovah's Witnesses have done a good job of convincing people that there are only two ways about thinking about most things, compartmentalizing them into "good" or "evil," "truth" or "false," "Jehovah" or "Satan." They have done the same with science, claiming their are only two sides to the issue, "evolution" or "Creation by God." Not true, don't fall into that trap.
Lastly, watch for the attitude from others that suggests that whatever choice you make is wrong. You might not choose to accept religion or God, but evolution isn't the only alternative for atheists, logical thinkers and scientists. Don't allow others to convince you as did the Jehovah's Witnesses that there is only one way to think, especially when it is the view they accept. Think for yourself, outside the box, pushing the envelope with courage. Great thinkers don't follow. Great thinkers lead.
