Birth certificates are worth the paper they're printed on and no more. Almost every single thing claimed in every single one of the videos is a lie.

There is no "serial number" on my birth certificate. The only number at the top of mine is the page number that was added when the certificate was inserted into the record book for my birth year. My name on my birth certificate is not in all caps. It's written in regular cursive handwriting. I did not get a social security number until I was old enough to look for a job. The claim that you can type the number into a site and see a value is bogus. Any random number you type in will return a search result. Total meaningless.

So it's all total and utter bullshit.
