,The Big Bang theory
It talks of a singular huge explosion unimaginable in physical terms.
Hydrogen and Helium formed sometime later.
The gases condensed under gravitation and formed the galaxies of
the present day universe.
In the solar system of the milky way galaxy, earth was supposed to
have been formed about 4.5 billion years back.
, There was no atmosphere on early earth.
Water vapour, methane, carbondioxide and ammonia released from molten mass
covered the surface.
The UV rays from the sun brokeup water into Hydrogen and Oxygen and the lighter
H2 escaped.
Oxygen combined with ammonia and methane to form water, CO2 and others.
The ozone layer was formed.
As it cooled, the water vapor fell as rain, to fill all the depressions and form oceans.
Life appeared 500 million years after the formation of earth, i.e., almost four billion
years back.
