There are only two acceptable answers to this question.
1. There is no God.
2. There is a God, but such a being is beyond the rational capacities of human beings.
As such a belief is God is simply a matter of choice. There are those who try to make logical arguments for or against God, but any logical argument made against God would simply be seen as the limitation of human reasoning in understanding God and any argument made for God is typically based on circular logic.
The watchmaker's analogy, as demonstrated by Captain, argues that the complexity of something is a valid argument for the necessity of a designer. While it is a fun and colorful argument, it actually disproves itself. If complex things must have been intelligently designed by something more complex than themselves, then something more complex than God would have had to design God. As such, the reasoning breaks down and you are left once again with the reality that God either does not exist or is beyond the rational capacities of humans.
There are other issues with his argument;
The single cause fallacy - God is the one and only cause of everything.
The possibly reversed relationship between cause and effect in the argument about Earth's perfection for the human life, which doesn't account for evolution of species or the climate and geological changes of the planet over time. We adapted to the planet as a species, the planet did not adapt or was made for us specifically.
There is also a problem with using Occam's razor to argue for existence of God - note the bolded "The principle is often summarized as "simpler explanations are, other things being equal, generally better than more complex ones." In practice the principle is usually focused on shifting the
burden of proof in discussions.That is, the
razor is a principle that suggests
we should tend towards simpler theories until we can trade some simplicity for increased explanatory power. Contrary to the popular summary, the simplest available theory is sometimes a less accurate explanation. Philosophers also add that the exact meaning of "simplest" can be nuanced in the first place
The thing that confuses me about creationist arguments is the selective use of science and and the apparent assumption that the biological complexity of life came to be instantaneously. If you assume it happened instantaneously, yeah, it doesn't make sense."
Creationism and Evolution have little similarities between them other than the same goal to explain how organisms came to be. The approaches to explanation are fundamentally different.
Then, I also have to wonder, how is God's creation, God being supposedly omnipotent and all, the simpler one?
Cause precedes effect, and I agree that everything has a "maker" in that sense. But why would the maker be God? Why wouldn't the maker be evolution? If we posit that the "maker" must be somehow more "powerful" than a mere human, and follow that line of reasoning, the big bang is certainly more powerful than anything a human might exercise, but it's not a valid response to a creationist. So, imo the line or reasoning quickly comes apart. What is interesting that it holds up if we assume that cause-effect relationship universally applies, and leave out the assumptions about the biblical God as the omnipotent ultimate creator entity.
Definitely, it all comes down to the paradox of knowing God. If God is in everyday higher than humans, and de-facto exists on a fundamentally different plane of existence and is a different entity allthogether, how can we perceive and know him correctly, is the question.
Philosophically I'm an agnostic, because my intellectual integrity doesn't allow me to ignore the possibilities or the problem or perception, no matter how small, but practically I'm an atheist, because I do not know God or his influence.
If you told me that God is a sentient entity ("big man in the sky") that objectively exists outside of humanity and is directing the storylines of the universe - I would disagree.
If you told me that you believe in the existence of natural forces that shape the universe, and you just prefer to call them God - I would agree, because natural forces exits, and it's not all too relevant what you call them, as long as you explain.
The difference between the two statements is that the first one implies a will, predetermination, a sort of destiny, and the other one doesn't. The thing is that the meaning that creationists conjoin with the creation is not necessary in any practical sense. This is where Occam's razor finds it's application. The Evolution does it's creative work without having a greater plan for humanity, and without being it's guide, and life survives and happens, and changes, the Earth spins and humans find their happiness, meaning and morality.
To remove apparent evil, we would have to be without the capabilities of morals and a sense of justice, whether it be subjective to the individual or objective to the whole of the human race. Murder would be classed as an act of the survival of the fittest, and rape would be classed as the insurance of the survival of the human species, natural evil as in disasters (I have no idea why some people call them evil) wouldn't be classed as anything, with no permanent emotional side effects (such as the death of a loved one). In other words we would be moral zombies or robots.
I'm astounded that you're taking the idea of survival of the fittest so literally and negatively.
Survival of the fittest means an organism is healthy, lacking impairing defects, being resilient toward illness, injury, food available, and climatic factors, and being capable of reaching reproductive age and leaving these traits to their offspring, it's not as literal as simple brute strength.
Rape is evolutionary bad, it's very bad in fact. It negates the whole mate selection process, it leaves the female vulnerable, and possibly unable to carry the pregnancy to term, it leaves the offspring vulnerable. Males are physically stronger than females generally, but it doesn't make him a good candidate for reproduction necessarily. What if the female is fit but the male makes the offspring inherit a genetic disease? Not good. Rape is extremelly widespread among ducks, and the females have evolved very long, maze like vaginas to circumvent fertilization by rape.
Do I even have to say why murder is bad from an evolutionary perspective? It thins out the population and leaves few reproductive choices. Bad again.
Grief and compassion keep us from harming other members of the species, which is again useful.
Moral sentiments are in complete accordance with evolution.
