One of my favorite sutta quotes can add to this topic.
Impermanent (anicca) are all component things,
They arise and cease, that is their nature:
They come into being and pass away,
Release from them is bliss supreme.
— Mahaa-Parinibbaana Sutta (DN 16)
I have read similar discussions to this one on so-called “skeptic” blogs and atheist forums and they never seemed to stop because of an endless pattern of circular reasoning and pseudo-philosophical nonsense. Ultimately, the view that nothing exists is, in my opinion, nothing more than delusional thinking. The Dhamma of the Theravada and modern scientific research share in the common view that the universe is impermanent (anicca) and always changing. There is nowhere in the Dhamma that says nothing exists and even if there were such a place, it would be inconsistent with the Four Noble Truths and the Buddha's other basic teachings.
