Jesus said he would return as in the *Days of Noah*
He says in Matt. 24:37-38: But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, (Gen.6-7).
Genesis 7
1And the LORD said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.
2Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.
3Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.
This could do with the DNA of Man and Beast.
We are now cross breeding animals as well as people.
“to keep seed alive upon the face of all the earth”
I interpret this phrase to mean that the birds were needed in order to scatter plant seed around the earth. Not only do seeds get scattered by the wind, but also farther afield, due to birds eating and dropping seeds from the mouths and from their scat.
