To Cecilia (Souls)
 
I do believe that even babies in in-vitro have souls, because the genetic components that GOD created are there---the sperm and the egg, it's just the initial vessel in a test tube or dish, then transferred to the woman's womb.  The egg and the sperm combined are injected with the soul. 
 
What I believe doesn't have a soul is a genetic clone, because it is man trying to play god with genetic components that would never occur in a naturalistic form.  Actually in an abnormal form, demonic if you ask me.  They use cells from a dead or live person along with an egg (who's or what we don't know), to try to clone a replica of that person or even an animal.  Also when man, through biotech companies are creating new creations that have never been seen before (mixing pig dna with human dna etc), I believe they do not have a soul.  I see clones as golems, creatures without a soul created by man.

what is a golem?

It reminds me of the joke about God and a scientist.  They were having a contest to see who could do a better job of creating man.  The scientist tells God, well you made Adam from the dust of the Earth, so can I.  God seeing the scientist picking up dirt to form something tells the scientist, "I created everything including the dirt.  You go and make your own dirt."  End of story.  GOD ALWAYS WINS!
