2. The CMB was radiated by ordinary matter. The atoms we're made of also radiated light 13.8 billion years ago when the universe cooled below 3000 centigrade, and those photons "we" emitted are now the CMB for "people" 46 billion lightyears away!
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
