Jesus said we would have no signs except those of Noah Methusila lived almost 1000 years aND DIED ONE WEEK BEFORE nOAH’S aRK WAS CLOSED.
You forgot to check that with Scripture. Noah was 600 when the flood rose. Lamech was 182 when he had Noah. Methuselah lived 782 years after he had Lamech.
So where do you get one week?
