I know not all organism need oxygen : e.g., anaerobic bacteria in the Earth's biosphere. With word limits, it is necessary to focus a little too much.
Regarding, ourselves in time AND space Kant posited before-after perception is internal and time and space are external and that causality might be a delusion. A coping mechaninism. The idea was dropped, after Einstein started working with space-time. However, Kant's concept re-emerged in the 1950s in the context of QM [from c.1900].
Even on Earth, finding life-forms over 600 million years old is difficult, because generally [not universally] soft-bodied creatures do not fossilise and if they do the fossils are often crushed by the build-up of rock sentimentation [Leakey] or destroyed by weather or displaced by plate tectonics.
The point about oxygen was that if primitive creatures tend be associated with low oxygen levels. If the aforesaid were found on Mars, it is a pointer to more advanced forms of life existing on planets with higher oxygen levels. It would show the "potental for life" is not merely an Earth-place phenomenon.
