Where did neutrons come from?

Inquiring minds want to know, where did neutrons originate from in the vast cosmos? Are they remnants of the Big Bang, or did they emerge in the hearts of stars through fusion reactions? Did they perhaps form within the cores of planets, deep within their gravitational wells? Did neutrons arise through some yet-undiscovered natural process, or were they crafted in laboratories by the ingenious minds of scientists? The question begs to be answered, and the search for the origin of neutrons remains a fascinating and ongoing quest in the field of physics and cosmology.
