In your opinion what causes christians to believe in Jesus

[Sheldon]

AI: "the Seventh-day Adventist Church generally believes in a young earth, typically estimated to be around 6,000 years old..."

Sheldon: If the universe is only 6000 years old, how is light visible from stars, that are billions of light years from the earth?

For the record, even when your own AI friend says Earth, you imagine that it says universe. Can I be blamed for not engaging with someone who even misinterprets those on his own team?

So you accept the fact the universe is billions of years old, and think this means you don't have to address the bat shit crazy nonsense you do believe, like a planet existing with vegetation on it, before the sun. 

You are funny, fair play...

Though this may not answer generally why Christians believe Jesus was a deity, it does explain why you could believe in unevidenced hearsay about supernatural magic, without any objective evidence. If you can believe the earth existed with vegetation on it, before the sun, then no belief is too absurd, obviously.
