In your opinion what causes christians to believe in Jesus

[John 6IX Breezy]

And thus for any definition of god that is distinguishable from nothing we have:

God ---> evidence
Not evidence

Evidence for God is ubiquitous, and that's the problem with requesting it. Scripture introduces God as the entity that made all things, and life in particular. Therefore, the existence of the planet and every living cell on it is evidence consistent with the thesis. To use your template: God ---> Life on Earth. And we observe life on Earth.

But you don't actually care about whether there’s evidence, you care about which interpretive framework fits it best and to be persuaded of one over the other.
