What does the Bible say about life before conception? I recently spoke with a friend of mine and he was wondering if we are alive before conception. We know that there is life after death according to the Bible, but what does the Bible say about "life" before birth?

All I could dig up was this:


  Jeremiah 1:4-5 (ESV)
  4&nbsp; Now the word of the Lord came to me, saying, 5&nbsp;  “Before I formed you in the womb I knew you,
  and before you were born I consecrated you;
  I appointed you a prophet to the nations.”


And this:


  Psalm 139:15-16 (NIV1984)
  15 My frame was not hidden from you
  &nbsp;&nbsp;&nbsp;when I was made in the secret place.
  When I was woven together in the depths of the earth,
  16 your eyes saw my unformed body.
  All the days ordained for me
  &nbsp;&nbsp;&nbsp;were written in your book
  &nbsp;&nbsp;&nbsp;before one of them came to be.


Any insight?

Edit: It is clear that we do not have physical being before birth but is there something in the Bible that might prove or disprove the existence of our souls before conception?
The Bible doesn't explicitly say whether or not we exist prior to conception.  The Psalm 139 passage you referenced indicates that God knew us before we were born and saw our unformed body.  However, this is not a definitive statement that we existed prior to birth.  Contextually, it seems much more probably to be referring to the omniscience of God (from whom I cannot hide, and who is with me wherever I go...)

It could be instructive to ask what would need to be in the Scriptures to give sufficient evidence for the belief in pre-conception existence.  If there were a verse that indicated God spoke to us or heard our prayers prior to conception or indicated we had made a decision prior to conception--those would be quite significant.  No such verses exists, though.  

In Psalm 51, David asserts that "I was sinful at birth, sinful from the time my mother conceived me"--but not before is mother conceived him.  This is quite a significant distinction.

Finally, if it were true that we existed prior to conception, we must wonder why nothing in the Bible explicitly or definitively states this.  On the contrary, we are given reasons to disbelieve this doctrine, but not conclusive reasons to believe it.  For a doctrine or idea that is characterized by such evidence it seems prudent to retain skepticism regarding it.
