First, I do not really know whether it should be part of my answer, so sorry if it shouldn’t, but ‘uncreated’ is not a very good rendering IMHO. ‘Non-created’, ‘free from being created’, ‘void of createdness’ work better for me, and these are markedly different terms with quite different implications. So,no for my reasons.
If you follow the Buddha, you can’t lose. If He’s correct, then you are on the right path and may ultimately attain Nibbana. If He was wrong and the Atheist position is correct, then yea, end of suffering after you die, no meditation required! Besides, if the death is the final end, then anything we do here is utterly pointless, so it doesn’t really matter whether we followed Him or not. But if there is even a tiny chance he was right, why not hedge our bets and listen to him? You don’t really lose much if He was wrong. You lose nothing.To me, this is the only religious tradition that helps us truly alleviate the fear of possible final death. Even if you firmly believe that death if the final annihilation, embracing or trying to embrace the anatta doctrine will help you realize that in some sense no-one dies and no-one lives, and the suffering of existence will not have much power over you anymore. There is suffering now, so what? You don’t suffer because there is no you, and this suffering will then just end one day.
Why should we follow the Buddha and no other religious traditions (apart from Atheism)? Because they have failed to provide me with a coherent and plausible account of what should be done and why. They tell stories, some of which are pretty exciting, some are boring, but most if not all of them inconsistent and with a fairly weak plot. The Buddha doesn’t try to tell only stories, one of His major points is that we should stop listening to all stories.
Another important factor for me is the brutality of the Dhamma. Many people think that the Atheism is a grim doctrine, but I think it is actually relatively optimistic, whereas the Buddhism paints a completely different picture: an immense ocean of suffering and nothing but suffering stretching into eternity on both ends with very slim chances to ever escape it. Adopt this teaching, breathe it in, soak yourself in it, and you will see how sober your view of the world will be. It is dark, it makes one anxious, but it is also very disillusioning.
Last but not least, His practical advice to both lay and monastic disciples is just great, be it meditation or ethical teaching, it improved me as a person and the quality of my life tremendously. My agnostic fiancée used to be a bit sarcastic about my devotion to the Buddhism (in almost all other regards I am usually far more sceptically minded), but after she had a few breathing meditation sessions, she read parts of the Anapanasati Sutta and seems to be interested in the meditational aspects of the Dhamma now. So, if it works so well, why not trust the Buddha’s other teachings? This is a fairly weak argument, I know, but it works just fine on the affective level.
