The days of Noah were destroyed by water, wheres the end of days will come by destruction via fire. These sickos are attempting to be that fire.
[2Pe 3:3-7 NET] 3 Above all, understand this: In the last days blatant scoffers will come, being propelled by their own evil urges 4 and saying, "Where is his promised return? For ever since our ancestors died, all things have continued as they were from the beginning of creation." 5 For they deliberately suppress this fact, that by the word of God heavens existed long ago and an earth was formed out of water and by means of water. 6 Through these things the world existing at that time was destroyed when it was deluged with water. 7 But by the same word the present heavens and earth have been reserved for fire, by being kept for the day of judgment and destruction of the ungodly.
