The assumption could be made that this bacteria is extraterrestrial.
...except it's not like they suspect this actual microbe is extraterrestrial, but the fact that it can substitute phosphorous with arsenic means life can be more diverse than what has been assumed before, which heightens the possibility of extraterrestrial life.
