Revelation 21:8 says:
But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars—they will be consigned to the fiery lake of burning sulfur.
Revelation 21:27 adds in reference to the New Jerusalem:
Nothing evil will be allowed to enter, nor anyone who practices shameful idolatry and dishonesty—but only those whose names are written in the Lamb’s Book of Life.
Given that the claims of young-earth creationism about both the Bible and science have been shown to be lies, falsehoods, half-truths, and deceptions time and time again, it seems to me fairly clear what the Book of Revelation says awaits young-earth creationists.
Obviously you can choose to reject the Bible’s teaching on hell/the lake of fire, and/or the Bible’s teaching about lies and falsehood. But you cannot accept both, and also be a young-earth creationist, without also accepting that you are destined for Hell.
