This comment posted on another site says it best :
I think one of the best examples of an honest man seeking the truth is Antony Flew. He was a vehement atheist for something like the last 50 years, convinced until just fairly recently that a God did not exist, that life evolved completely accidentaly, and even at one point, that humans had no free will. In other words, he was a hard-determinist).
But then, by honestly looking at the evidence, he came to the conclusion that a God had to exist (although he is a Deist and does not believe in an afterlife) and that the genetic coding within DNA is prime example of intelligence. He was also inspired by the careful balance of the cosmological constants and natural laws and this sort of thing.
As far as ever becoming a theist, he said he is definitely open to the idea and says you cannot limit an omnipotent Being except for the logically impossible (such as a round square). He says he never knows what may happen. One day he may hear God speak to him, saying, Can you hear me now?
If everybody was this honest, we wouldnt have these angry, raving atheists (not all, but those such as Richard Dawkins) and evolutionists (again, a prime example being Richard Dawkins) screaming at others for doubting their faith.
In the case of the atheistic radical Darwinists, it seems to have set in as some sort of adolescent crisis and the monkey bones mythology with its elaborate pictures and graphs seems to provide a sort of secular Illustrated Children's Bible for them. But they do seem to be Freudian sexual anxieties behind the anti-Christian hysteria. The real question is why obsessing on pictures of imaginary prehistoric ape men ( and demanding that others do so) seems to relieve the anxieties for them. You would have to study when the adolescent crisis set in and what series of events led to the fixation on the prehistoric ape men mythology as a solution. Something makes them feel comforted by obsessing on pictures of large, imaginary, prehistoric ape men. It may be a little like the geeks and nerds who turn to comicbooks with images of ultra-muscular superheroes like Superman, Batman, Spiderman, Captain America, and the Flash. Just a little more like the Swamp Thing monster obsessions.
There's always some kid in middle school, usually awkward around girls, who can't stop talking about Bigfoot, Sasquatch, Lizardman, the Wolfman, or various other mythical boogiemen and rural swamp monsters. It seems to be of that type. Then you see a sickly Victorian neurasthenic like Huxley latching on to this with obsessive-compulsive fury. Something psychological -in abnormal psychology - seems to be behind this. Most normal people don't get this hysterical about their hairy monster fantasies. Or it goes away when they finish puberty.
