Alrite, one point at a time --
Refuting the first cause argument
Vezzellda said:
Can you honestly be completely confident in saying that this whole hugely complex and amazingly precise universe is just an 'accident' with no purpose as to why it exists and no direction towards which it is heading? "When we hear the sound of an unexpected explosion, we instinctively ask what caused it. Why not ask the same question when faced with the biggest explosion of all?" (John Blanchard)
Claim:
Every event has a cause. The universe itself had a beginning, so it must have had a First Cause, which must have been a creator God.
Response:
1. The assumption that every event has a cause, although common in our experience, is not necessarily universal. The apparent lack of cause for some events, such as radioactive decay, suggests that there might be exceptions. There are also hypotheses such as alternate dimensions of time or an eternally oscillating universe which allow a universe without a first cause.
2. By definition, a cause comes before an event. If time began with the universe, "before" doesn't even apply to it, and it is logically impossible that the universe be caused.
3. This claim raises the question of what caused God. If, as some claim, God doesn't need a cause, then by the same reasoning, neither does the universe.

Refuting the lack of purpose argument
Vezzellda said:
I am all for science telling us how the universe works and how it started and am amazed by the minds who worked out such complex ideas, but science doesn't tell us WHY the universe even bothers to exist in the first place.
Claim:
If man arose by chance, life would have no purpose or meaning.
Response:
1. Purpose can come from anyone. The same object can have different purposes to different people or to the same person at different times. If you, or anyone or anything else, want to do something with your life, then your life has purpose. Nothing else is relevant.
2. Purpose is not determined by origins. Things can have purpose even if their origin is due to chance. The North Star, for example, came to its position by chance, but people still find a purpose for it.
3. Like most people, virtually all creationists already acknowledge that people arise by chance. In the process of sexual recombination, it is chance which determines which genes come from each parent and thus determines the genetics which make us who we are.
4. The theory of evolution most emphatically does not say that humans arose purely by chance.

Refuting the human emotion argument
Vezzellda said:
Science cannot explain how the human mind exists and functions as it does. Humans have huge capacities for love, friendship, reason, logic. We have a conscience, an innate sense of what is right and wrong, of justice, we have a feeling of community with our fellow human beings. How can these qualities been a result of a "biological accident?"
Claim:
Evolution doesn't explain human personality, emotions, and the human mind in general, which make man distinct from animals.
Response:
1. Once the brain and consciousness have evolved, emotions, personality, and mind may be unavoidable. They certainly have selective advantage. Emotions serve to motivate us. And people without personality tend not to get laid.
2. People who have had pets know that cats, dogs, even birds also exhibit emotions and personality.

Refuting the human morality arguments
Vezzellda said:
If there is no God, why do we feel that we have to treat our fellow humans with at least some dignity and respect? If we say that there is no God and so no reason why the universe exists and no goal towards which it is moving, then we should be behaving as if there is absolutely no rational or moral order. We would have no concerns about massacres or genocides or rapes or the destruction of forests.
Claim:
Evolution cannot explain moral behavior, especially altruism (evolutionary fitness is selfish; individuals win only by benefitting themselves and their offspring).
Response:
1. The claim ignores what happens when organisms live socially. In fact, much about morals can be explained by evolution. Since humans are social animals and benefit from interactions with others, natural selection should favor behavior that allows us to better get along with others.
Fairness and cooperation have value for dealing with people repeatedly [Nowak et al. 2000]. The emotions involved with such justice could have evolved when humans lived in small groups [Sigmund et al. 2002]. Optional participation can foil even anonymous exploitation and make cooperation advantageous in large groups [Hauert et al. 2002].
Kin selection can explain some altruistic behavior towards close relatives; because they share many of the same genes, helping them benefits the giver's genes, too. In societies, altruism benefits the giver because when others see someone acting altruistically, they are more likely to give to that person [Wedekind and Milinski 2000]. In the long term, the generous person benefits from an improved reputation [Wedekind and Braithwaite 2002].
Finally, evolution does not require that all traits must be adaptive 100% of the time. The altruism which benefits oneself most of the time may contribute to life-risking behavior in some infrequent circumstances.
2. This claim is an argument from incredulity. Not knowing an explanation doesn't mean no explanation exists. And as noted above, much of the explanation is known already.

Refuting the stupid arguments
Vezzellda said:
Throughout history mankind has had a sense that there is something bigger than themselves, they have searched for an actual meaning to life and for their own place in the universe.
A 'sense,' while interesting, is not a reason. Not only does it not show anything, but I would hardly say it is part of every individual. Moreover even if it were, having a feeling for purpose is valuable in determining one's own purpose. It does not indicate that we are looking for the purpose that was "given to us," rather it may be that we are looking for a purpose of our own choosing.
Vezzellda said:
Also, you can ask why has faith in God been impossible to destroy? [...] Would people die for something they knew was a lie or something they were just blindly convincing themselves of for the sake of something to hang on to?
1. That is a loaded question. These people don't obviously believe they are "blindly convincing themselves of for the sake of something to hang on to." They truly believe it. But that doesn't make their beliefs right! This is a ridiculous position to take. It's like saying that if I was willing to die for something, it must be right.
2. You have made an appeal to majority (a lot of people believe it, therefore it is right) and tradition (it has been around for a long time, therefore it is right), two major fallacies.
Example 1 (majority): a huge number of people believe the Earth was flat, therefore it is flat.
Example 2 (tradition): We have used slaves for hundreds of years, so it is okay to keep doing so.
[I am not the author of any of the "claim" and "response" refutations. I'll deal with the God and morality thing seperately.]
