A person does not exist till birth.
A statement of belief, not fact.
Age is measured from birth not conception.
Here, that is true. It is not necessarily true everywhere. But, regardless, it is totally irrelevant.
Sperm, eggs and embryos can all be frozen, then thawed and still viable to continue on into life. Once birth has occurred, we cannot freeze a breathing person and bring them back.
Is it a lack of technology or could it be that we cannot freeze and then thaw "life"?
I'm gonna go with: you've been drinking.
