    Earth has been around for 4.5 billion years. For 4.3 billion years life has existed.

    That is, at minimum, 4 billion years of animal farts we’re breathing in with every… Single… Breath…

      I don’t think bacterial excretions count as farts, so it’s probably more like 800 million years worth of farts as that’s when animals started existing.
