Here is a short video that explains why we can be confident that the New Testaments we read today are translations of the original. There may be variations in the manuscripts, but these differences are minor and easily sorted out by text criticists. The text you have today is based on the original.

interesting video thanks for sharing it.
There have been manuscripts found in Hebrew of the book of Matthew. I would consider this more original than the Greek text any day.
