Did the Bible ever mention China, Australia or other continents?

no it only mentions the middle east and some parts of africa and greece and rome cause that was the whole world back then they had no knowledge of the americas or china or japan

Hm...this should be interesting, the most it says would be other lands or something...but other than that, zip and nada about any other lands...therefore since the Bible doesn't say them, they must not exist, right? *gasp* So that means there can't be any illegal immigration since Mexicans can't cross the border or something? Or that there can be no Bush since he was born in Texas...but since we can see and experience the world with our own eyes, that means that everyone believes that there are countries named China, Australia, America, etc...right? So what's so wrong with science then, if it's almost the exact same thing? Just wondering...anyway, hope I helped you some way...^_^

The quick, direct answer is no.

However, Jesus did say:

"You will be witnesses of me both in Jerusalem and in all Ju·de′a and Sa·mar′i·a and to the most distant part of the earth." Acts 1:8

It shows Jesus was indeed aware that other areas on the planet did exist.

Of course not, the author did not know about those areas. And according to the bible the world is flat.
