“ONLY if those alien parents were already naturalized citizens.”
No. The only exceptions were for the children of ambassadors, and those born to an invading army.
And Obama’s father was here legally for years studying at good schools. Nor is Obama in any sense an illegal alien who has invaded our country.
But if he'd been studying at some podunk community college it would have been a different story? :)
"Here legally for years" doesn't mean he became a citizen, ever. There is no documentation that BO Sr. ever became an American citizen. A citizen of Australia (for example) who works here but has to go back home every six months to renew his visa is here legally also, but he still isn't an American citizen.

[I] find no fault with the introductory clause, which is simply declaratory of what is written in the Constitution, that every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen.
