glycolysis is the most ancient glucose oxidizing pathway?

Another bit of evidence supporting the idea that it is the most ancient metabolic pathway is that virtually every organism on earth metabolizes glucose by the same steps catalyzed by homologous enzymes. So, it must have evolved very early and passed down without change ever since.

I think so. Glycolysis is found in all living cells. While in aerobic condition provides pyruvate, anaerobic condition leads to production of lactate(in most cases). Indicating that the pathway survived the changes in the composition of gases in atmosphere.

they say it is ancient because it can occur without oxygen. so pretty much, back in the day when there was no oxygen, things could still survive from production of atp from glycolysis.

I'm not sure if you're looking for confirmation or evidence or ...?
