You are confounding two separate things. There is no minimum age for passing on "natural born citizenship". The law on age of the parent concerns births outside the US, where one parent is not a US citizen. But it only affects "citizenship", since "born outside the country and to one non US parent" precludes natural born citizenship anyway, by either criteria.
And remember Congress can not define by law "natural born citizen". They are the ones who wrote the parental age laws.
WHEN ARE WE GOING TO SEE OBAMAS BIRTH CERTIFICATE?

Then who can? If Congress is tasked by the Constitution with rules for naturalization then don't they first have to define who doesn't need to be naturalized?
Yes, Obama’s father was a Kenyan (at the time of Obama’s birth- a British colony).
Let’s see Obama’s passports, Indonesian school records, Occidental College school records AND the original birth certificate.
