There are two historical events that shape the narrative of the Bible and they are the creation and the flood. These two events are the foundation of much of our understanding of world history and our current day understanding of life. Within those two stories lies the explanation of why is a plant base diet best for us, why everywhere one can travel shows evidence of a major flood, where the sun, mountains, plants, etc. comes from, why are we here, etc. Yet the Bible predicted of a time before the second coming when there will be a big push to question these stories. Today we can say we are seeing this prophecy being fulfilled.
2 Peter3:3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 3:4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as [they were] from the beginning of the creation. 3:5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
3:6 Whereby the world that then was, being overflowed with water, perished: 3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
