Wow such insightful comments from everyone have really made me reflect deeper than I would've anticipated! With that I guess I would rephrase my original question from when we "get" our soul to when the soul enters our physical body. I was a bit up in the air when I first posted the philosophical question however after thinking about everyone's responses I'm more of the opinion and maybe like to think that "I" as in- my soul- resided by the Father until being called to Earth, and after physical death will return to Heaven.

On a side note, a little story told to me by my mother got me thinking..maybe you all have an opinion on this too..

My mom had me and i was very sick at birth, as a result I had to undergo operations but not before my mom was sent home many times by the doctor thinking mom was just jittery being a first timer. Mom was riddled with guilt over this time and thought maybe she wasn't fit to be a mom and should give me up to more "capable hands"..to which her brother (who converted to Mormon) said to her- "No, your daughter knew you before making her choice to come to Earth, she chose YOU to be her mother."
It's a very honouring feeling to think our children chose us to be their parents.

Do you have thoughts or an opinion on this?
