Oxygen was discovered in 1773. How did our ancestors breathe before then?

We are gathered here today because our ancestors didn’t have condoms. I think I’ll just sit here and waste oxygen all day. If trees offered Wi-Fi, we would plant more of them. Too bad they only produce this oxygen thing. So proud of my ancestors for crawling out of the sea and evolving lungs. Pretty disappointed in them ever since though.
