Ad Personam Fallacy

Personal preferences, dislikes, or weaknesses used as a reason to believe

Examples:

A much better conclusion would be that everything started with a big bang billions of years ago.

This disbeliever thinks it’s a better conclusion because it’s the conclusion that the disbeliever prefers.

That’s what I believe because that’s what I prefer to be true.

Truth is truth, and we can’t understand it or know it based on personal preferences. If someone prefers something to be true, this person can probably find someone preaching it somewhere. What does God say? That’s the only relevant question.
