我找到的温度、大气压适宜的terra大气里全都是二氧化硫、甲烷之类的……没一个含氧的……

找到过有氧气的，基本都是荒漠行星

有氧气的都不是正常行星。。。

Oxygen is very reactive, and thus usually forms compounds with other elements rather than existing in its own molecular forms. So things like H2O, CO2, CO, SO2, etc. will be common, but O2 is extremely rare. The only reason we have a lot of it in our atmosphere is that photosynthetic life produces it.
搞错了，其实是HarbingerDawn说的作者本人根本就不管

其实有可能别人那球上的光合作用根本不是产生氧气的→_→

的确找不到有植被的含氧气的类地行星全是SO2

这个有点玄
