It is based simultaneously on the latest data from astrophysics, planetary geology and the origins of life on Earth, all of which are evolving as we continue to study them. It could be said that exobiology is essentially Earth-oriented, as it’s based primarily on knowledge learned here that we try to apply to other possible or observed situations.
