We don’t know if life started in the light though and then migrated to the vents and adapted. My memory of it is that this is an unanswered question so far.

It's definitely an open question. But in his book "The Vital Question", Nick Lane makes an interesting case that they're actually the origin of all life: https://nick-lane.net/books/the-vital-question-why-is-life-t...

We know that life is older than photosynthesis. I'm not aware of another light-dependent metabolic process that could predate chemosynthesis.
