Yahweh.
God´s real name is Yahweh but Elohim, Adonai, Jireh, Shadai, Tzevaot, El Elyon and Abba are also very popular and important in christianity.
Of course Allah is also a real name of god in Islam and there are people believing that Bhudda is god.
It is also interesting to be thinking about the translated versions of the word god as for example Gott (German), Gud (Swedish & Norwegian), Dieux (French), Dios (Spanish) Dio (Italy), Kami Sama (Japan), Prah Jau (Thai), Bog (Russia & Poland), Patmeshwa (Hindi), Shangdi (Shen) (China) and Jumala (Finland) and of course Theos (Greek).
Jehova has also become a popular name of god.
Some eastern religions consider Vishnu and Rama real name of god. Maybe Shiva...

Get the Just a namemug. Though we all know Obama's last name will most likely never be truly discovered, some may argue that his last name could be "the second", and judging at his full name from google, "Barack Hussein Obama II", I would agree
P1: hey, P2, have we found out Obama's last name yet?
P2: sadly, I don't think so.
P3: actually, his last name is "the second", look it up!
