The scientific community is exclusively materialistic. Your soul is not material so it doesn't exist. They believe your self-awareness, consciousness, is merely neural connections in your brain, and they assume it dies when you die. In the same way, they believe that if we could build a computer with the complexity of the brain, then it would become conscious and believe it had free-will, just like you!
You would be considered a dualist - a human has a material body with an immaterial soul (conscious). You would normally accept that people born from artificial means still have souls - this includes twins, clones, or other forms of genetic engineering to give birth to people.
