What did they "take no note of"

Matthew 24:39
They chose to be unaware.
They were aware of what they did not avoid,
when it came sudden, a deluge, a flood.
Jesus said it will be the same.
They are unaware to avoid that which is to come.
Unbelievers put on arrogance.
Believers put on unbelief.
Like a drunk person they care not.
It's like they put their faith in superman.
What they worship is not God, it is hero worship.
That is how unbelievers are ahead of believers.
