The question just gets pushed back a little further - where did the Higgs boson come from? Did it create itself? John 1:1-3, Colossians 1:16, Hebrews 1:1-2.
The question was not “where does mass come from”, but “how do particles gain mass” - a subtle, but important distinction. You may think that religion will give you all the answers, but those answers are all in the form of “God did it”. Science never asks “who gives particles mass”, because “who” is irrelevant. It is the “how” that matters, because knowing how something is made to happen allows us to make it happen when we choose. Religion tells you that God is the source of everything and if you want something to happen, you must ask God to do it. Science tells you how things actually work, so that if you want something to happen, you can make it happen through your own actions. It is this spirit of self-reliance that forms the primary difference between science and religion.
