CITATION NEEDED! You are stating your opinion but it feels like you are pretending to have some scientifical knowledge...
I don't need citation to prove that 2 + 2 != 5.
Yes it is my opinion, but not only is it a generally accepted opinion, it is overwhelmingly accepted. I could find some polls for you that prove this, but I'm not sure they would meet your moonlanding-was-faked level of scientific scrutiny...

No, it's not. According to Webster:(1) : the state of being united to a person of the opposite sex as husband or wife in a consensual and contractual relationship recognized by law
(2) : the state of being united to a person of the same sex in a relationship like that of a traditional marriage.
So if MY GIRLFRIEND
and I decide to have children and we live together happily forever, we CAN'T say we are married unless we were recognized by law.
Marriages can exist without the state contract, also known as the marriage liscense. Marriages in India exist without Oklahoma issuing a liscense. Depending on the jurisdiction, you could be considered married even without any official liscense.
In fact I bet YOU couldn't distinguish who is the son of what kind of parents.
No, I couldn't. That's what variation is all about. For example, a tall father is correlated with a tall son, but that doesn't mean that tall fathers WILL have tall sons, or that tall sons WILL have tall fathers, but that the father's height will correlate with the son's height. The son will probably be closer to the average than the father, but the taller the father, the greater the expected height of the son. I wouldn't be able to simply declare that because you are a tall son, you MUST have had a tall father. If you absolutely need citation for that, I would recommend Sir Francis Galton's paper on that http://www.jstor.org/pss/2245330
In the same vein, I couldn't declare "because you are a criminal, you MUST have come from a single parent", or "because you are successful, you MUST have had both parents", as children from married couples can become criminals too (and people with one parent can become successful), but I CAN declare that "children from broken homes/single parents are more likely than children from marriages to become criminals".
For the citation, I'm sure I can find something better for you, but\ http://janicehiggins.bizopiaweb.com/Portals/48411/pages16-17.pdf
is the first thing I could find.
