So now you already dont know this thing that who is your real father. so D.N.A test means you admit that you need help of your real mother. so in all respects you have to approach your real mother.

and now if you also dont know your real mother then what is meaning of such so called D.N.A test ?

same you have to follow real authority. "Whatever You have spoken, I accept it," Then there is no difficulty.

Otherwise, if you makes research, "Who is my father?" go on searching for life; you'll never find your father.

Correct, I don't know for sure if the people I think are my biological parents are actually my biological parents. If they're not, they're still the only parents I know, and I'm fine with that. I have no particular reason to want to confirm or disconfirm that. If I wanted to find out, I wouldn't need to approach my real mother. I could have my mother tested and if she is not my real mother, that's that.

A DNA test can conclusively prove whether a given individual is a biological relative. We get half of our chromosomes from our mother (plus mitochondrial DNA) and half our chromosomes from our father. DNA sequencing is a reasonable way of determining paternity and maternity if such is in doubt.

Real authority can be readily ascertained, the first step is to establish that the claimed authority actually exists and is not just some people trying to exercise authority on behalf of something they've dreamed up to give themselves an imaginary basis to claim authority. You can usually tell them by their claims that the being that they're speaking for can't be proven not to exist.

If I never find my 'real' father, so what? The one I have is enough, whether we're 'the same blood' or not. Who I'm biologically related to is trivial compared to who actually raised me.
