In your opinion what causes christians to believe in Jesus

[Sheldon]

The problem with sourceless-light is that it will kill you and it'll do it very quickly.

One second you argue light can't exist without a source, and the next you're arguing  that sourceless-light can actually kill you. Which one is it?

Existing after the source has gone, and not having a source at all, or having a magic source, are clearly not the same, and for context, the light that reaches our planet from other solar systems, regardless of whether those stars still exist, would not be sufficient to sustain vegetation on this planet...

More pointedly, your creation myth states that "all the stars" were created after our planet existed with vegetation on it, so a double fail...
