So I took Keras' post as a reference and decided to check those numbers for myself and so I created a spreadsheet.
I was not able to confirm that exactly
2,000 years had passed when Abram arrived in Canaan. In fact, my spreadsheet shows that at that time
2,021 years had passed.
I also ended up with a different number of years to the Babylonian exile. Keras said it happened at year
3,386.5 but my spreadsheet tells me it happened at year
3,384.5. I don't believe this number really matters anyway, but I just wanted to point out that my calculations are quite different.
However, the really exciting part is that my spreadsheet does indeed confirm that exactly
4,000 years had passed from Adam to when Jesus was baptized, and I find this quite amazing and fascinating. I don't know why some of my other numbers differ from Keras but the most important point in my mind is that God waited for exactly
4,000 trips around the sun before Jesus was baptized. This tells me that nothing in God's plan is random.
I don't know how to share a spreadsheet so I took a screenshot of it that I can share right here.
Now keep in mind that the Bible gives us years, but nothing more specific. So when it says Asa reigned for 41 years (for example), we know that's likely not exactly 41 years but we don't know if that's 41 years and two months or two days or even a month or two shy of 41 years. It's just not that specific, so because of that this can not be considered 100% accurate, but at the same time over the course of 49 events being calculated in years only, the law of averages tells us that this likely averages out quite well, with some numbers being just a little bit too big and others a little too small.
