Fighting for god(s)

[Aoi Magi]

well, in your hypothetical scenario, we could start simply by having actual proof of existence of said parents, then we could move on to further analysis and even DNA tests if required. Your god fails at the very first step though...

So.... In your little world even ADOPTED PARENTS share DNA...

The reason I specifically chose 'adopted' parents over biological ones is not all universally an adopted parents right/claim over an adopted child. Therefore "proof' of parenthood becomes arbitrary to anyone who does not want to recognize the relationship or bond...

Kinda how the whole God thing works now...

Why would a dna test only have to be about matching DNA to biological parents? DNA testing has a lot of applications, but even in your simplistic scenario it could be used to determine whether the parent claiming to be the birth parent (or creator of child) is a liar or not...

And no, if your are an "arbitrary" parent, you'd most likely end up in jail. Foster parents need to prove themselves to retain their rights to raise the child...
