Hi Sassy
This biblical scholarship is fascinating.
Both Abraham and Noah were ancestors of Jesus Christ.
For the time being, we'll forget about Noah, and just look at the ancestry of Jesus. The Bible gives the genealogy of Jesus and, just as you say, he was descended from Abraham in a direct line of descent through 42 generations.
According to Archbishop Ussher, Abraham lived about 1900 years before Jesus. This means that the
average age of each of the ancestors in the line of descent was about 45 at the time of the relevent conception. Seems a bit old, to me but we'll accept it. And because they were so relatively old it is also likely that several older siblings had already been produced - it was before the days of Marie Stopes, after all.
Anyway, let's assume that each of these patriarchs had just two children, and that each child had just two children. And of course, we know that Abraham only had one because the Bible says so - so that means wear looking at the progeny of 41 generations.
So 2 raised to the 41st power is:
1,199,020,000,000
Abraham's potential issue over 41 generations would be 1.19 trillion. That's more than a hundred times the present population of the planet.
No wonder Jesus could clain descent from Abraham. So could everyone else, including all the apostles, Judas Iscariot (ok so he was one of the apostles anyway) Herod Antipas and Pontius Pilate as well.
Both Christ and the Jews knew Abraham existed because the circumcision and covenant made handed down from Abraham.
I suspect that ritualised male genital mutilation had alrady been around for a long time.
Maybe you need to understand that the bible is true for many reasons and one reason is that Christ and Abraham both existed and without Noah then none of them could have existed.
There is no evidence that any of them existed. There are stories about them contained in the Bible. Using this argument I can say that Dumbledore and Ron Weasley both existed.
Now, I fear that we have derailed a topic about a very serious and meaningful subject. Let's get back to Hiroshima.
