The very young often make the mistake of thinking that Resurrection and Reincarnation are both the same. It is not so!
Resurrection is "bringing the dead back to life". Many believe that Jesus was Resurrected.
Reincarnation means "living again". All animal bodies decompose; they rot. The chemicals that the animal was made of go into the earth, and they enrich the earth, and feed the plants. Then the plants feed the animals. And so, everything that lives, dies, and lives again in another life-form.
I'm not talking about "spirits" here! I mean the actual flesh that rots.
