I guess courage was not distributed equally to all through the evolutionary process and money is needed to sweeten the pot for such an important topic to be publicly discussed.
Numerous articles by scientists have appeared in the last 10 to 30 years challenging various key aspects of the Darwinian theory.
700 scientists who dissent from neo-Darwinian evolution and have signed a statement of dissent “There Is Scientific Dissent From Darwinism. It deserves to be heard.” The list is growing and includes scientists from the US National Academy of Sciences, Russian, Hungarian and Czech National Academies, as well as from universities such as Yale, Princeton, Stanford, MIT, UC Berkeley, UCLA, and others. (DissentFromDarwin.org) “We are skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life. Careful examination of the evidence for Darwinian theory should be encouraged.” http://www.dissentfromdarwin.org/links.php
The evolutionists know once creationism is acceptable and taught alongside evolution theories their house of cards crumbles. So they are fighting with all they have to prevent this.
The god that atheists don't believe in, does not exist, as many have noted they are arguing not against Christianity but their wrong view of it. It would be advantageous for atheists actually took the time to know the Christian worldview and what the Bible actually means, not just what it says before they leap into arguments against it. But if they did this they may risk conversion.
