In order for you to automatically become a citizen at birth, you must be born in the USA or your Parent be born in the USA if you are in the US, Puerto Rico, the Virgin Islands, American Samoa, Guam, or the Swains Islands.
So it matters where you are parents are born. If they were US citizens, which would make sense because one of the children is a US citizen, and you were born in one of the above countries, then yes, you can. But if you moved to somewhere like Greece, then you would be a Greek citizen, not an American one.

Person can become a US citizen by being born to parents even if one of them is a US citizen or by birth if born in US. Another way is through the naturalization process by filing Form N-400 person can become a citizen.
It's the place you were born. If you were born in USA you are a native American citizen. ---- You don't become a native citizen. Either you are or you aren't, as noted above. To become a naturalized citizen is another story.
