Just off the top of my head, scientists could test for changes in brain chemistry such as increases in dopamine levels while eating bananas. They could also test for positive reinforcement as it correlates with dopamine levels. fMRI could also be used to map specific brain functions and further correlate the ingestion of bananas with feelings of euphoria or pleasure. So how would you run similar experiments with the "God did it" explanation? You can't, can you. We can show how science can answer these why questions. However, it would appear that theology can not. All theology can do is indoctrinate people into a belief system where they think they have answers, but in reality they do not. What they have is beliefs. Beliefs and answers are two different things. Answers require knowledge. Beliefs are the antithesis of knowledge. Theology is devoid of answers. The Emporer has no clothes.

My position is that science does a fine job of explaining why we are here. Our own personal existence is explained quite well by biological reproduction. As Modulous mentions above, evolution does a great job of explaining why our species exists. I have explained in previous posts my position on religions inventing purposes and intentions as it relates to nature. Perhaps a bridge hand will better illustrate what I am talking about (bridge is similar to spades or hearts if you are familiar with those card games). After you have been dealt a hand you could ask yourself why you were given those specific cards. But why would you? You could have received any one of millions of possible 13 card hands, each of them with an equal probability. You have the hand you have because that is the hand you got. It is that simple. There is no divine purpose or evil intention in the cards you received. It is simply one outcome of millions. I think this does a good job of explaining nature, and by extension us. We are but one result out of trillions of possible results. Given the march of time, one outcome had to occur just as it was inevitable that you would have a 13 card bridge hand. Science does an excellent job of explaining why we are a possible outcome of that process, and in explaining the historical events that led to that outcome. As to my larger worldview, I see a universe that is indifferent to our existence. The universe cares about our existence to the same extent that we care about the plight of a single bacterium stuck to the underside of a rock in the middle of nowhere. The purpose that does exist in our lives is the purpose we give it. Purpose is not an external or intrinsic property of the universe. Instead, it is nothing more than our hopes and dreams of how the universe should be.

Another creationist who laughs at real science. Go figure. quote: Edited by Taq, : No reason given.

From my point of view, it is.
This reminds me of Lucy jerking the football away just before Charlie Brown kicks it. When someone states that science is not capable of explaining the "higher purpose" of human existence do you think that they do not believe in a higher purpose or see nothing meaningful in this higher purpose? We are told that this entire universe full of trillions of stars was made just for us, and that this creator has a purpose for us to fulfill during our lifetimes. We are told that we are extremely special, and have an immortal soul that needs saving. Should we really think that the same people who make these claims are saying that "eh, it isn't true and not that meaningful, but it's what I believe"?

Even then, uncertainty can be expressed as a probability that is derived from first principles. Science does a wonderful job of explaining why nuclei decay, and the probability of a single nuclei decaying over a set time period. The fact that no one can predict which nuclei will decay next, or exactly when a given nuclei will decay, does not negate the explanation. If there is a quantum-like feature of brain activity then science still does a fine job of explaining why we do one thing and not another just as science does a fine job of explaining why one nuclei decays and the other does not.

For a valid answer to the why question we only need to understand the fundamental aspects. To use an analogy, we can't go back in time and use modern radar and satellites to measure the causes of thunderstorms. However, detailed study of some thunderstorms allows us to answer questions of why thunderstorms occur, including those that we did not observe or measure. The same for brain activity. Once we understand the general mechanics of decision making we have the answer to the why question in specific cases.

Purpose and mechanism are one in the same. What is the purpose of Grandma choosing tea over coffee? A fundamental knowledge of how the brain works can answer that question. It can be due to reinforced positive feedback from previous cups of coffee, caffeine addiction, etc.
Why not?

A properly controlled experiment may not be what you think it is. Controls are there so that you can trust the measurements you are making. For a brain scan, a control can be as simple as proper contrast within the imaging procedure.
You don't need to control that anymore than you need to control the weather to understand how it works.
