Every version of Thor has been Odin as father and the embodiment of the earth as his mother. That is why he is midgards protector. Jord in norse mythology, actual not comic, is Thor's biological mother, Jord is the embodiment of the earth, the norse Gaea. You have no reason to believe that this is not the case as it always has been through every incarnation of THor ever made.
