このような奇妙な生物そして彼らの生き方を研究すると実はこれはすごく効率のいい生命体でしたそして彼らは古細菌「太古の者」と呼ばれていますそしてなぜ彼らが「太古」なのかというと彼らが生まれた時代はこの地球が電池中の硫酸のようなものに覆われこの地球が電池中の硫酸のようなものに覆われまた溶けた核と一体でその時鉄を食べて生きていたからです
So, when you think of odd life forms, when you think of what it takes to live, it turns out this is a very efficient life form, and they call it an archaea. Archaea means "" the ancient ones. "" And the reason why they're ancient is because this thing came up when this planet was covered by things like sulfuric acid in batteries, and it was eating iron when the earth was part of a melted core.
