Don't confuse motivation with veracity. While it is certainly reasonable to be weary of a claim made by one with ulterior motives, don't assume the claim must be false simply because the person making the claim will benefit from your acceptance of the claim. Arguing that a claim is false based solely on this assumption is known as the genetic fallacy.
Example: Of course Joe believes these stats about the likely extinction of the spotted owl—he volunteers at the National Wildlife Federation.

If you spent your life assuming "God" was the answer to all of life's biggest questions, but can no longer believe, you might have many questions that begin with the phrase, "If there is no God..." If there is no God, how did we get here? If there is no God, what's the point of life? If there is no God, where does our morality come from"? If there is no God, won't the world collapse in anarchy with murdering, coveting thy neighbor's wife, and eating shellfish? These are just some of the common questions to which there are good answers. These courses will help you build a strong foundational secular worldview based in science and reason.
