Soyeong: The Big Bang wasn't suggested because it sounds good, but because there is cosmological evidence that it happened. Of course it's possible that the evidence could be misinterpreted, but it's possible everything could be misinterpreted, so that shouldn't stop us from drawing conclusions to the best of our ability. William Lane Craig makes a big deal out of the universe having a beginning, and I think
we should go with what science says until better evidence suggests something else, but there is sufficient philosophical reason to think that the universe had a beginning, even if we can't rely on the scientific reason.
No, we should not. Until we can prove how universe was created via experimentation or observation (quite difficult to do, I know), we should do all in our power to disprove the theory of Big Bang, regardless of how likely it is. Dwelling on a single idea brings stagnation, and exploring alternatives to that idea may either yield more solutions or even solve problems which seemed completely unrelated. We should never 'Go with what science says' until it has been proven without shadow of a doubt to be correct.
Furthermore, it is exactly as you said -
philosophical discovery. Now I'm not belittling philosophy - it's extremely important in exploring areas beyond our current understandin to try and explore all possibilities, until some of them become a scientific hypothesis and that, in turn, a serious theory. Without philosophy and the initial thoughts and logical conclusions, none of this would be possible. However - until relatively recently, the most logical conclusion, a conclusion supported by many philosophers, religious figures and
written text, was that the Earth is flat. That the entire universe orbits around us. All of these conclusions are perfectly rational and logical, given the infomation and knowledge contemporary civilizations had - they didn't really have much choice in the matter as they could not possibly prove the truth. Why was it so? Because philosophy makes logical leaps. It has to for it to function.
But without sufficient information you can't claim a statement, as logical and sound as it might seem to us, to be the only logical explanation. Let me start off by saying that humans are stupid. Our brains are not capable of even grasping the concept of vastness of our galaxy, let alone its history or even its beginning. All of these concepts are so incredibly alien to us, with our current level of knowledge, that claiming -any- answer is definite regarding the issue is a fallacy all by itself. We quite simply do not have information to know anything. As likely, nice or popular any given explanation might seem, it doesn't change the fact that we only really know the Earth, we have a good amount of information about our surroundings, very little from the rest of our galaxy, and pretty much bugger all from the other galaxies. Mankind is extremely inexperienced and needs perhaps even thousands of years of dedicated research and exploration to be able to come to a satisfactory scientific conclusion.
In light of all this, I will not trust a conclusin that we, with our current amount of information, and our current level of knowledge, might consider 'logical'. Because it most assuredly is not the only logical answer.
I will not argue about whether or not universe was created by a sentient being, intetionally, because I can't know that. Neither can you. Neither can anyone else on Earth.
Soyeong: It's not about arrogance, but about the nature of logic. If an argument has true premises and an a valid form, then the conclusion logically and necessarily follows.
True. But the argument can't possibly have true premises until we aquire more information. You can't just leap from what we know to the creation of the universe, that's completely illogical at worst and wishful thinking at best.
