    I am in agreement with you. I believe in creationism and intelligent design. Having said that, I don't mind going along with the notion that God (who I believe was the creator) could have used many things that scientists hold true and call "evolution" and the "Big Bang" to get us to where we are today. I think there is enough evidence to suggest that I can't be closed-minded about this. I for one have no problem believing that the earth is millions or billions of years old. However, I have friends who subscribe to the "Young Earth" theory which I find an interesting theory, but not very likely and not based on scientific evidence.

    I don't try to tell people that don't believe like I do that they are wrong...I just want to have the same right to believe that which I do without being called a moron, fool, etc. just because someone else doesn't agree with it.

Books evolve. 15-year old books don't have much to difinitively say on the cosmological constant, either, though they may be perfectly good texts on all other phenomena.

    Actually, religion looks at mythology and people's opinions about theology, morals, the proper social order, and the existence of a lot of unevidenced supernatural stuff.

    > The main difference is science is trying to constantly disprove itself while religion is trying to prove itself. They are not opposing forces just different methods of trying to find truth.

    Religion, most often, merely attempts to maintain traditional beliefs and values. Those who are "trying to find truth" usually get kicked out of the club, because truth is rarely deferential to traditional beliefs.

    Second, there's a difference between being open-minded and just plain trying to justify remaining religious while supporting popular scientific theories. Personally, as a believer in what I guess is called the postmodern philosophy, I'm extremely skeptical about most things, especially things of universal magnitude. I just don't think there's any evidence whatsoever to suggest intelligent design is possible, and there's plenty of evidence to the contrary that the Divine Scenario and the Scientific Scenario are completely and totally mutually exclusive. The truly open-minded cannot ascribe absolute faith towards any one theory, or they risk alienating the possibility of other ideas (and you realize that christianity, judaism, islam, et. al. depend on absolute faith); therefore, the only options you have are to either admit that you absolutely believe creationism and assert with ultimate certainty that god created the universe, or to assert that you depend on scientific evidence, and that you cannot express with complete certainty that god created the universe.
    Also, I don't think calling someone a moron or a fool because of their beliefs is wrong. I think it's a dastardly thing to do unless you actually show evidence supporting your point of view, but I think calling people idiots and fools is an integral part of the free exchange of information; and aside which, they're not getting any more intelligent with you patting them on the back and saying "good idiot".

    I intend to be called an idiot and a fool in response to this, and also probably be modded down as much as my karma can stand, but this just has to be said. That's what I believe.

Then there is an other group who believes that their religion is the full truth and anything to prove the otherwise is evil.

Religion on the other hand is more of a combined study where you put together many different studies and look at the truth as a whole, and if science can't 100% prove it, other theories are fair game, if they fit within the philosophy better.

    Strawman to the nth degree.

    Your comment reveals a profound ignorance of what science is about. Anyone who believes science reveals truth doesn't understand science. Science is the search for fact. not truth. As Indiana Jones memorably said,
    Archaeology is the search for fact... not truth. If it's truth you're looking for, Dr. Tyree's philosophy class is right down the hall.

    Furthermore, the purpose of science isn't to "solve problems"; it is the search for fact.

    And ever since the scientific revolution and the Enlightenment displacing Rationalism in the 18th century, science never seeks to prove anything. In science you can disprove, but you cannot prove because of the principle of skepticism. So the statement "if science can't 100% prove it, other theories are fair game" makes no sense at all.

    The purpose of science is the search for fact. Science is the study of the natural world. Religion and philosophy are there to provide commentary on and understanding of the human condition. From that perspective, they have nothing to do with each other and should not be mixed.

    A little more on this. Science does not necessarily have to solve problems. Science can in fact merely find a reasonable explanation for known phenomena, and then show that said explanation is consistent with other phenomena and, even better, predict something we have never noticed before. A prime example of this is the bending of light around the sun.

    The issue of truth is not so crucial. There is nothing wrong with looking for truth. There is only something wrong with the arrogance involved in thinking one has found it. Science, at it's best, looks at the world in hope of one day finding the truth. It is seldom that the scientist believes they hav found the truth, or has the arrogance to state that the revealed theory is hogwash based on personal belief. In such cases, the revealed theory still wins.

    The problem is really that the people who attack science tend to confuse themselves with god, and believe not only that they have the capacity to understand the truth, but that they have found it. In fact, the truth is the sole provenience of god, and it is the privilege of us lower being to examine the creation and try to understand some of it.

    The situation gets worse as the arrogance goes beyond the belief that one is god, to the belief that one is such a wonderful god that one can put the entire truth of creation into one text. At this point stupidity replaces arrogance, as all that can be done is to fit new fact patterns in existing theories of existence. A person who does such a thing is arrogant, stupid, and corrupt beyond the ability to be saved by any messiah, prophet, or wise person. Such people are best locked up in the ghetto of an old sports arena, so their disease can be contained, and the harm to civilized society minimized.

These simplifying assumptions are so useful in everyday thinking that we apply them until they lead to problems. Then instrumentation becomes more economically tempting.
