Various theories of origi'l of life on c-arth are reviewe-d with reference to
possible development of similar life forms on other planets of other solar
systems. Extraterrestrial origin of life on earth (pans~rmia hypothesis)
is discussed critically from moment of a spore's escape from another planet
to the arrival on earth's surface. Life on Mars, Venus, and other planets is
briefly discussed. Conclusion of speculation is that intelligent life does
exiat in other parts of the universe.

From questions on the nature and characteristics of life, the author proceeds
through theories on chemical evolution vrith the establishment of an environment
conducive to the origin of self-replicating macromolecules. Speculation on life
on o\'her μlanets. life elsewhere in the solar svstem. and life in the galactic
systems ~s followedbv a disc11ssion of man's pla-::e in ihe universe. Of the two
hundred million inhabitable planets ir1 the visible uni'.:~rse, two areas selected
for attempt at interstellar communication (Project Ozma) are Tau Ceti and
Epsilon Eridani,

Current knowledge of chemical evolution on earth and the generation of
molecular communities which give rise to terrestrial organisms is reviewed.
It is hypothesized that given a corresponding set of molecules, temperature,
and environment anywhere else in the universe, a similar sequence of
evolution might have oco:urred as on earth. Mars is considered the most
likely possibility for organic life.

Traces chemical evolution to the point when a primitive organism is formed.
Applies this reasoning to question of whether we are liltely to find that
similar events have occurred elsewhere than on earth.
