What happened four thousand years ago? This is the end of the sixth day because Adam and Eve were in the Garden of Eden 6,000 years ago. So that makes this the beginning of the seventh day. Or Pentacost was almost 2,000 years ago. So the this will be the third day for the Christian Church, what some call the Holy Spirit Dispensation or the Age of Grace. The flood of Noah was around 4,359 years ago. So I do not know what you are referring to that had a beginning 4 or even 5 thousand years ago. Some people sense Adam there was 2,000 years of lawlessness, 2,000 years under the law and now with the Church Age we have had 2,000 years of Grace.
