杏瑤：

說某一東西已有很久歷史是 It is something ancient.

這件文物已有5000年歷史是 This relic(文物)或antique(古董) has existed

over five thousand years.

如說這件文物已舊到年代無從稽考就是 This relic has existed since time

immemorial. 句子中不必要提到歷史的字眼。

e.g. This antique has a history of 5000 years.

This cultural relic had in 5000 history

this is an antique

this xxxxx a aged old

this xxxxx was found a aged old

a long long time ago

more than 5 thousand years

since 2990 B.C. ~~~~ 2990 + 2010 = 5000 years

用 it has a long history就得啦!
