The history goes back to 650 years ago.与The history goes bac

意思上没什么区别.语气上,第二句更好.
前一句有点象是中国式英语.
请参考下面例句：
1）The history of electricity goes back more than two thousand years,to the time the Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two.
2）The history of life insurance goes back to ancient times.
