Have they not all got MEDICAL INSURANCE?
Are they not trying to AVOID what Evolution has in store for THEM and their families?
Not to mention that evolution is in direct contradiction to Christian morality.
If evolution is true, then our highest goal is simply to propagate the species, and the highest goal for any individual is to propagate their own genetic material. So, as a man, if I were to take evolution seriously, I should be trying to sleep with as many fertile women as possible, to maximize the chances that I having living offspring to keep my genes in circulation. That is not compatible at all with Christian sexual morality.
