It's virtually impossible scientifically speaking, to pinpoint the exact date, the exact moment of conception. But it's obviously much easier to pinpoint when a child is actually born, hence a "BIRTHday." But regardless if we can't record the exact moment, the child nevertheless comes into existence the moment they are conceived and a brand new unique human organism which had never existed and never will again, is created.

If you have to use fertility treatment (IVF) you do know when your child/ren were conceived, when they implanted, etc.
True. Though that's not exactly the most common way conception occurs.
You are correct.
