The study of Abiogenesis can be geophysical,
Many approaches to Abiogenesis investigate how self-replicating molecules,
or their components, came into existence.
Earth remains the only place in the universe known to harbour life,[29][30] and fossil evidence from the
Earth informs most studies of Abiogenesis.
Nonetheless, Earth remains the only place in the universe known to harbour life,
and fossil evidence from the Earth informs most studies of Abiogenesis.
In general, all modern theories of Abiogenesis imagine some scenario in which natural conditions create,
combine, and arrange molecules in such a way that they begin to self-replicate.
This concept has expanded a great deal as mankind's understanding of science has grown,
but all forms of Abiogenesis have one thing in common: they are all scientifically unsupportable.
The study of Abiogenesis can be geophysical,
chemical, or biological, with more recent approaches attempting a synthesis of all three, as life arose under conditions that are strikingly different from those on Earth today.
