There are no means to determine an objective "good"? Also, how does reason alone come to the conclusion that all actions are equally good or bad?
It sounds like you never had any deep reflection on the subject. There is simply no way for raw reason alone to prove that one definition of good is better than another.
I'll try to give you a simple example. Let's say you consider that committing murder is objectively bad because every being should be allowed to live as long as humanly possible. But who is to say that after death, one does not continue to live as a soul in some sort of fantastic realm like heaven? Then, under that logic, murder could no longer be bad because it does not end one's existence. There are countless such arguments for every single moral value (e.g. murder is bad, helping the needy is good, etc.).
And, wouldn't that conclusion be an objective definition of good if it were a definition defined by man?
No. By definition, good is what's better than bad (obviously). If no action is better than any other, then there is nothing good or bad. All actions are equally meaningless.
Also, why couldn't there be any reason to exist without good or bad choices? Maybe the point to living could be custom constructed by each individual and modified at the individual's will. For example while playing MMORPG games, there often is no clearly defined overarching goal that players strive toward, instead players construct their goals during gameplay, which in turn creates meaningful and enjoyable play. If you take this mode of playing and apply it to real life one could enjoy their life by constructing and striving for their own goals -is that not meaningful?
This is precisely what DavidJCobb mentioned in a previous post to which I already responded. Giving your own arbitrary meaning to your existence is tantamount to saying that there is no such objective meaning. Most of you fail to understand the gravity of this thought.
A reality without objectivty is tantamount to a reality born from your own thoughts; a reality that is the product of your imagination alone. To know that you are one lonely being in a seamless nothingness, that there exists not only none other greater than yourself (which is awful by itself) but also no other thinking being like yourself is the most awful thing; think of it as being immortal and buried alive. I certainly would not want to be a God (that is, there exists no being whose knowledge of truth is greater than one's own) and I most definitely would not want to be the only existing being.
Objectivity being inattainable does not directly imply that nothing exists outside one's self but it certainly points in that direction. Think of it this way: if you are buried alive without any way of ever escaping your coffin, what does it matter if there is a world bustling with life outside?
I think it really depends on the reasons you believe in God. Between having random values and believing in Him for fear, I take the first alternative as being better and even healthier. Maybe David somehow referred to such situation, in which you cannot do whatever makes you feel good due to religion's rules.
However, your case is different: you have your own thoughts and conclusions about that, and I would even say that your choice is more solid and viable in the meanings of having a good life since it makes you have less dillemas and unanswered questions than an atheist or a skeptical would have.
What? You probably did not mean to be rude but I am still slightly insulted by this. Faith is never a question of fear. Yes, some shady men of religion use it to spread the "good word" just as some politicians cultivate fear of terrorism or communism to get votes.
Also, you're saying that faith is just an escape to all of the big questions ("you have less dillemas and unanswered questions than an atheist or a skeptical would have.") which is a blatant generalization. It was common for societies in the early stages of their cultural development to believe in supernatural beings to explain certain phenomena like thunder, rain, etc. In our modern era however, faith does not serve the same purpose (in most cases I know of). If you read my previous comments, you would know my reasons for believing.
None.
