The
KJV translates the Greek word for "
escape notice" as "
ignorant".
2 Peter 3:5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: [kjv]
3:6 Whereby the world that then was, being overflowed with water, perished: [kjv]
Today, most scientists deny that the flood of Noah ever happened - given the geologic features present today.
The idea in the Greek is that they willingly let it escape their notice.
Peter uses the same word again a few verses later.
2 Peter 3:8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. [kjv]
This last verse has the implication that God is outside of time and space as we know it.
We should not let this thing "
escape our notice".
