Quick Facts From The Old Testament Flood Story About The Length of Time It Took To Construct Noah's Ark
How long did it take to build the ark?
- Many bible scholars and historians believe that it took between 52 to 75 years for Noah to build it in the story of Genesis to survive the flood.
- The length of time it took to build it shows the longsuffering of God, not willing that any should perish but that all should come to repentance.
- There isn't a conclusive verse in Genesis or in the entire Bible that gives the exact length of time for the ark's construction.
- Many believe that it took near 100 years for Noah to build it.
- We know that it most likely took less than 100 years to build and that based on the bible reference of Genesis 6:3 that Noah had 120 years to build it, but several passages show that it was not 120 years to build it.
- Most bible scholars put it at less than 100 years.
- The scholarly consensus is that it took around 52 to 75 years to build the ark.

How Long Ago Did Noah Build The Ark?
- According to Bishop Ussher, the earth was created around 4004 BC and the flood took place around the year 2350 BC.
- This would mean that the flood took place around 4374 years ago.
- Since Noah took some time before the ark was completed before the time of the flood, it's safe to say that Noah's ark was finished around 4474 years ago (give or take).
