Have you combed through every single account of anamnesis, recorded and unrecorded, in order to make this universal claim? 

Did you mean that they only claim to be reincarnated Jesus, Napoleon, Caesar, etc.? That if reincarnation was true, they would reincarnate as lesser-known figures, or characters from other dimensions/worlds?

Its the universe incarnating as itself when a new body is formed. When you die, you go into a field of all knowing awareness of everything, and your knowledge is uploaded into the collective consciousness. The soul knows all things, and that is why it knows the past lives of other beings.
