Days of Noah

God says in the Bible that the last days will be similar to the Days of Noah, so maybe we should become more familiar with that era. Here is what the Bible says:

Matthew 24:36
Heaven and earth will pass away, but My words will never pass away. No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. As it was in the days of Noah, so will it be at the coming of the Son of Man.
