CERN describes anti-matter as the Mirror universe of our matter universe.
I see anti-matter as the spirit world.
A whole universe of symbiotic spirit living next every atom.
With this concept in mind then all things have spirit. But not all things are reaped into the anti-matter universe.
Most antimatter goes back into its sub atomic particles and lives in a massive pool just like the ground.
What anti-matter/spirit is reaped?
1st all mortals are grown and reaped.
2nd some animals are reaped also not all,
to be used again in another Earth like world.
3rd Some plants are also reaped to use in starting other worlds.
