You need one existential crisis step further. With very rare exception (some life we've found living near thermal vents in the deep sea) all calories are derived from the sun through photosynthesis. I suppose you can muddy the waters with man made light sources powered by non-solar energy, but with the rare exception of nuclear power (or tidal, since that's moon's gravity, or geothermal, and a few other niche sources, but even out together these make up such small percentages), most man made energy is just harvesting the sun's energy with more steps. Oil, that's just ancient plant matter. Wind, that's just air currents which only exist due to heat energy from the sun. Solar, lol. Not that grow lights even make up enough to matter, but it's a fun part of the existential equation.

We eat the sun.

Just salt me and call it a day; I'm ready for the next stage of human diet

Mushrooms are fucking gross dude. Imo instant dish ruiner.
