In your opinion what causes christians to believe in Jesus

[Sheldon]

‘Without form and void.’ SDAs generally believe in a young Earth (though you yourself may not) and a literal interpretation of scripture.

Does formless and empty mean non-existent? No; the narrative is literally one of preparing the planet for life, and not of creating a planet from scratch. I don't know a single SDA that would argue otherwise.

Perhaps you just fell for the nominal fallacy: You've heard the term Young Earth Creationism online in atheist circles and assumed the name gave you some kind of insight into people's actual beliefs.

A young earth is no more compelling than a flat one, and for the very same reason.
