1. God is formed in the image of man.
The funny part of this statement is that it's at times suggested that if there is a god, he wouldn't have human traits, or bother with communicating with a mere human on an individual basis. The problem with this of course is that it's a preconceived notion of how a god would be. It's still a very human
idea that may have it's roots in the idea that people in power or are famous generally don't associate with the common man.
Another way to look at it would be, perhaps man being made in God's image is why we possess some of God's traits that actually originate from him.
2. Christians are afraid of death.
Well, some are, and some are not. Some atheists are, and some not. I guess the idea in some cases might be that it's a manhood issue. A bravado thing. It's a terrible argument because accepting provision for eternal life is no less cowardly than accepting provision given to us by law enforcement, the military, etc. Unless one really thinks that isolationists who hide out in a cabin in Idaho ready to attack anyone(s) including the law are braver than those residing within civilian law are braver. And even if we concede that they are braver, is that really an intelligent approach?
3. If God existed he would make everything crystal clear to where there would be no need for a Bible, or the Bible would be completely understood the same by everyone.
This is particularly interesting, because we humans tend to value study and hard work in general. For instance, most people given a hypothetical option of either going to school and learn via study, or having a computer chip placed in our brains giving us all the information we need to know, thus the school experience (the prom, playing sports, friendships, etc.) are no longer needed, most people would probably favor going to school and study. We value the ability to learn from experience and personal research, and the right to think for ourselves. Why would this be any different concerning the Bible and the study thereof?
