Philosophical Question about Consciousness

[willie24]

Scenario:
John Doe dies today. Immediately afterwards, in another part of the world, Jane Smith is concieved.

Philosophy # 1: When John Doe dies, his world has ended. When Jane Smith is concieved, her world has begun (out of nothingness).

Philosophy #2: John Doe is reincarnated as Jane Smith, but without any memory of John Doe, or any physical/psychological connection to him.

Is there a difference between the two philosophies?
