It's arrogant to believe that years of study by learned scholars is absolute non-sense and that you have had the answer all along due to you advanced connection to God. That is arrogant.
It is not arrogant however to believe that you do not know the truth but wish to seek out evidence of the truth. It is not arrogant to participate in the discovery and science.
I will never understand how anyone can think that the Christian "always right because God said so" mentality isn't completely and absolutely arrogant. When non-Christians who make no claim of advanced knowledge are being self-glorifying.
EDIT: Also in regards to your examples of paintings and cars, you already know that those things are man-made. You cannot work to discover the truth from the assumption that you already know it. If you had never seen or heard of a car before you would have NO idea that it was a man-made device.
All of this of course completely disregards everything that I've pointed out, including the objective facts that the Bible predicted the theory that you put so much stock in, and that people would find "evidence" of what they were choosing to believe thousands of years before those scientists existed. I'm not being arrogant by acknowledging that a being that is far, far greater than I knew everything about the way our bodies function and the way our minds would work, right down to the exact ideas that many of us would base our lives upon many, many centuries prior to our births...I'm placing emphasis on HIS knowledge, not on that of myself (which I would be if I were so arrogant). My faith in God humbles me, causing me to admitt my own weakness and need for salvation from someone else, as I would not believe I did if I were so arrogant.
To discard God and put full faith in humanity alone is to discard the need for that humility, we all came from animals, there is no absolute right or wrong and we can just make up whatever happens to work for us, there is no being out there that is higher than us that we are to be judged by since we just got here without one and hence can make up whatever rules we happen to like and totally discard God...this is human arrogance, whether people that believe in it would like to admitt it or not. Just the fact that so many non-believers find the very idea of being bound by God's judgment offensive only serves to confirm that.
The point of the examples I gave was simply that regardless of who had created them, they (and in the case of the car, the very specific functions) are too elaborate to simply get there own without a creator, obviously, hence things that are vastly more elaborate are also too elaborate to have gotten there on their own without a creator, obviously.
It's right because God said so...and he said it thousands of years before the humans that you put your faith in EVER EXISTED, and to this date, none of the many predictions that he made through his prophets has ever been wrong. Everything about our minds, bodies, the political and environmental state of the world...perfeclty supports what God said in the Bible, that is the backbone of the Christian belief of things being true because God said so. It's not simply a matter of "it is...because it is" as non-believers make it out to be.
