Those people simply accept other people's ideas without really observing the world. The world is so wonderful,There must be a creator.It is discouraging that so many see hard times as chastising. Many others see hard times as God teaching us lessons. Christians should see that, and in Islam it is more explicitly stated.
In my opinion, creationism and evolution are knit together. As Creation matures, and various creatures time comes to an end perhaps we could learn? I have encountered various people, some well educated who attempt to use that process to say that the Creator does not exist. Sad.
