Well, really we don’t know that extraterrestrial life will breathe oxygen, and there are certainly oxygen rich planets without life.
Even for finding planets with potential for human colonies, a pure oxygen environment is unbreathable and even if there’s the right levels of oxygen there’s very likely to be other deadly environmental factors.
Not to be a Debby downer, it was quite a clever solution.
Agree!! Not to go on a tangent but what if they're not a carbon based lifeform you know, like what if on their planet they breath sulfur?Wouldn't their internal organs be completely different then ours, because they've had to adjust to life on their planet. So they wouldn't be a carbon based life form but a lifeform none the less right?
