Brandon notes the possibility that Ive always been around but ... have a lousy memory of my pre-birth existence.
Since JazzO quoted T.S. Eliot, let me supply an elegant passage which bears out Brandon's idea perfectly:

Our birth is but a sleep and a forgetting:
The soul that rises with us, our life's star,
Hath had elsewhere its setting,
And cometh from afar:
Not in entire forgetfulness,
And not in utter nakedness,
But trailing clouds of glory do we come
From God, who is our home.
- Wm. Wordsworth from Intimations of Immortality

BTW, I don't believe Ive ever seen so large a number of posts on one thread in a single day. Kudos to tsuwm for introducing it.
