- I can sleep with whomever I like, because if evolution is true, there are no standards of right and wrong (Atheist - pg 163);
- I fear encroachment of God in my personal life (Atheist – pg 164);
- Evolution eliminates any need for God (Creator – pg 77);
- Evolution frees me from somebody being accountable for my actions (Creator – pg 25, 41);
Evolution allows me to pursue personal happiness and pleasures at all costs (Creator – pg 77); and
- I can remain free from the perceived moral restraints of God (Atheist – pg 164, see also Strobel’s Case for Faith, pg 91).
Do I use evolution as an excuse to be immoral? When I was a Christian, I did not smoke, I did not abuse drink, I did not take drugs, and I was in a happy monogamous relationship with a wonderful girlfriend. Now that I’m an atheist, I do not smoke, I do not abuse drink, I don’t take drugs, and I am in a happy monogamous relationship with a wonderful wife (for those who are wondering: the girlfriend and wife are the same person). Morally, I haven’t changed that much since I left the faith. I’m still, well, basically me.
So if a desire to be immoral is not the reason for my belief in evolution, what is? It’s not a result of my non-belief in God, as I’ve explained here. Rather, I believe in evolution because (1) the evidence for it is extremely good, and (2) to quote the famous evolutionist, Theodosius Dobzhansky (who was a Christian, by the way): “Nothing in biology makes sense except in the light of evolution”.
Let’s briefly explore these two reasons:
Evidence for evolution: who can ignore the many lines of evidence from the large variety fields such as botany, zoology, geology, palaeontology and anthropology. There are many clues from the fossil record, atavisms, biogeography, pseudogenes, and endogenous retroviral infections, that point to the idea of common decent. For a more detailed discussion of the evidence for evolution, read 29 Evidences for Macroevolution at the TalkOrigins site.
Making sense of the living world: why do animals, including humans, have ‘design’ flaws in their bodies? Why do some whales grow hind limbs, and in some cases even feet, within their bodies? Why do most marsupials live on the isolated landmass of Australia? Without evolution, these questions don’t have answers. When I finally accepted the idea of common decent, the entire field of biology became all the more wonderful and beautiful – simply because, using the paradigm of evolution, I could begin to understand some of the intricacies and mysteries of the living world.
