Each time a discovery is made and revealed. Or hidden for many reasons. Eventually the truth comes out of whatever the findings reveal.
These discoveries bring us back closer and closer to the real Judaism of how it was thousands of years ago. Noah, Abraham etc. are different people, The one commonality in all these people up the prophets is their faith in GOD.
As we get to closer to the end more and more discoveries will be made. This will offer Israel many lessons to be learned.
