Would "know" they existed is not the same as they "don't" exist.

You see, there is a reason that words are used so you can really define things and be clear on them.

What I was saying is women blather on about stuff and men don't.

As for custody, it appears today that woman don't really want custody.  They want to pawn of child caring duties to the father so they can just hang out.  Men on the other hand take child rearing seriously and are happy to get the kids.  Unless the woman is punishing them - which does happen.  I will keep the kids and you give me all the money.
