Life obviously starts at conception, but the questions of personhood are different: Is a foetus a person with human rights ab initio? What is the legal significance of the heartbeat? Where and when does the soul come from? etc etc.Fucking hell. I'm a Catholic (non practicing) and I don't know anyone who thinks we get 'injected' with a soul at birth. On the other hand I know plenty of people who believe that life begins at conception. i.e when sperm meets egg.
