I think the problem is you can always rationalize for why something COULD exist if you really wanted to. So instead of looking at things and thinking "hey, this doesn't make sense and here's why" many religious people will try to find the most reasonable explanation that justifies their beliefs. It turns it into "hey, this doesn't make sense, but here's why it could." For example, I can say there's a monkey in my closet, I just can't find him because he's really good at hiding, can camouflage himself, and can even blink out of existence if he wanted to. If I don't acknowledge there's no way the monkey COULDN'T exist (he must be there!), then there has to be SOME explanation as to why I can't ever find him.
And to make things worse, when a reasonable explanation can't be found, they just say "God is beyond logic and reason" which is totally impossible to argue against.
