As i said earlier in a answer, I do not reject science but i follow the teaching of Buddha sakyamuni. And according to the teaching everything contain the 4 elements.
Before you say Buddha is wrong ( you may think he is) The teaching have worked for many buddhist since buddhas time And personally i have no doubt in the teaching (probably like you have no doubt in science)
Nobody prior to 1800 had the modern theory of atoms (there was an ancient one, but it was quite different). Nobody prior to 1900 knew anything about nuclei.
One reason alchemy failed is that it had the wrong basic philosophy: that of 4 elements. When the modern concept of elements was formulated, the science of chemistry was produced.
When did buddhists look inside of an atom?
