atheism and children

[SteelCurtain]

A certain level of medical intervention for fertility so you can reproduce is perfectly moral. It's when you take it to the level of taking complete control of it by physically doing it yourself on a petri dish that we don't think is moral. Likewise, getting a baby out of the womb is not the same as actually creating human life.

I still don't understand what the difference is between placing a fertilized egg in the womb of parents who are incapable (through plumbing or motility, etc) of doing it with sex and taking that baby out of the womb at the end of the cycle. Is it more moral if the parents have sex before or after implantation?

I guess it's the word immoral that I am hanging up on. This implies that you think that two people who want a child of their own have done something wrong by creating a child using medical intervention, the same medical intervention that helps cure cancer, saves a baby's life that is born with some defect, or comes up with a polio vaccine. Why is this specific medical intervention immoral, but other fertility methods aren't? IVF doesn't do anything other than put the egg and the sperm together and implant some embryos where they grow inside the mother. I am just confused as to where the line is drawn, and how a person as intelligent as you obviously are wrestles with this internally. When do you decide that certain medical interventions are God's plan that we discover and utilize (modern medicine), and others are against God's plan (IVF)?
