Why do people deny evolution?

All I asked was if you were prepared to condemn the Srebrenica massacre and those who deny that it happened.

For whatever one may allege LF's mindset to be, it is undeniable that he provides no evidence, and does not enlist science in his cause. He's not stupid, and he may well be intelligent. He may be well educated. All of that, however, goes by the board because of his dedication to his imaginary friend superstition. His method is not dissimilar to that which BJ has always employed. That's to attempt to control the conversation with two cheap tricks. The first is diversion, and almost always involves references to abiogenesis. The second is ipse dixit pure and simple (although BJ does this much more often). We are expected to believe just because he has said it.

No appeals to civility or intelligence can take away the twin facts that LF (and BJ) present no evidence, and try to avoid discussing the topic

All information has an author.

We already know that DNA evolves naturally (no author), so your statement is demonstrated incorrect immediately.

Current models
There is no single, generally accepted model for the origin of life. Scientists have proposed several plausible(Plausisble but some how impossible to replicate. comment by bj) hypotheses, which share some common elements. While differing in the details, these hypotheses are based on the framework laid out by Alexander Oparin (in 1924) and by J. B. S. Haldane (in 1925), who postulated the molecular or chemical evolution theory of life.[102] According to them, the first molecules constituting the earliest cells "were synthesized under natural conditions by a slow process of molecular evolution, and these molecules then organized into the first molecular system with properties with biological order".[102] Oparin and Haldane suggested that the atmosphere of the early Earth may have been chemically reducing in nature, composed primarily of methane (CH4), ammonia (NH3), water (H2O), hydrogen sulfide (H2S), carbon dioxide (CO2) or carbon monoxide (CO), and phosphate (PO43−), with molecular oxygen (O2) and ozone (O3) either rare or absent. According to later models, the atmosphere in the late Hadean period consisted largely of nitrogen (N2) and carbon dioxide, with smaller amounts of carbon monoxide, hydrogen (H2), and sulfur compounds;[103] while it did lack molecular oxygen and ozone,[104] it was not as chemically reducing as Oparin and Haldane supposed. In the atmosphere proposed by Oparin and Haldane, electrical activity can produce certain small molecules (monomers) of life, such as amino acids. The Miller–Urey experiment reported in 1953 demonstrated this.

We cann logically assume that the information in the codes of qm biochemistry and DNa have an author just like the codes that come into existence today. That is a logical assumption made from observed patterns.
