There's a theory that life actually originated not directly through photosynthesis based life, but originally from a very constant source of energy - the earth's crust - Hyperthermophile archaea - using non-oxygen based metabolism which migrated to the surface where photosynthesis evolved and took over as the core energy source.

All laid out in Paul Davies' book - fascinating read: https://www.simonandschuster.com/books/The-Fifth-Miracle/Pau...

Actually this is not a theory. Photosynthesis came millions of years later than life. Plants are evolved from animals, not the other way around. Basic animals are less evolved than basic plants.

Plants and animals evolved from different lineages of eukaryotic organisms. They share a common ancestor, but plants did not evolve from animals. Plants evolved from green algae, while animals evolved from colonial protists.

I also take exception with the concept of "more" or "less" evolved. Do you mean "complexity"?

He is right though that, "Photosynthesis came millions of years later than life." And the parent post's claim, "There's a theory that life actually originated not directly through photosynthesis based life," misrepresents that it is a commonly held view that life originated not directly through photosynthesis based life. It is generally understood that life predates photosynthesis.

Yes, they are right that photosynthesis came later, but then veered way off track saying that plant evolved from animals.
