When did you get here?

It is said that when a child first moves in the mothers womb, that is when that child's spirit enters its body, it then become a living being. Until then the child is but a growth, so to speak, in the woman's body, sustained like any other organ.

Now as to how did you get here. Every person was a spirit before coming to earth. At a command from Heavenly father that spirit leaves its heavenly home to come to earth as a new born babe, to be tried and tested. The veil is very thin between this world and the world of spirits. How it is all done is not yet revealed, but all in due course all will be revealed.
