"37But as the days of Noe were, so shall also the coming of the Son of man be. 38For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, 39And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be."

"27They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all. 28Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; 29But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all. 30Even thus shall it be in the day when the Son of man is revealed."

"If Jasher’s account is correct, it indicates that pre-Flood mankind had highly-advanced laboratories which could map the genomes of animal species and which had the technology to transfer DNA from one species to another species’ embryo to create mixed (or “chimera”) species. Indeed, might pre-Flood mankind have eventually mixed animal and human DNA together as well? I think the answer is “yes” because Jesus Christ prophesied the latter days would mirror the pre-Flood world of Noah and mankind is already able to create such chimera species today.
It is possible that chimera species are already living on the earth in laboratories and hidden locations."

"It is extremely serious to tamper with the integrity of man as transmitted through his DNA. This is, in part, what triggered the flood in Noah’s day. All of the hybrid humans were destroyed during the flood"

"Another element of the Days of Noah is the genetic manipulation that took place during the days of Noah. It’s a difficult subject for many to accept or admit"
