Evolutionists believe that God did not speak the world into existence as He claims He did in Genesis and elsewhere in the Bible. They also believe that a global flood never occurred. God warned us that in the last days, both of these false beliefs would be common.

Knowing this first, that there shall come in the last days scoffers,
walking after their own lusts, 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.
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: Whereby the world that then was, being overflowed with water,
perished:
II Peter 3:3-6
