Did life first evolve 2 million years after the Big Bang ?

We suggest24 the time of first life was at ~ 2 Myr when the universe cooled sufficiently for water
to condense, with stardust fertilizer C, N, O, P etc., at the core of the H-He4 primordial planet
clouds, Fig. 9. The critical temperature of water 674 K approximately matches the breakdown
temperature of amino acids needed for DNA, and permits the high speed chemical kinetics necessary
for living organisms and their complex chemicals to rapidly develop and evolve the highly efficient
DNA mechanisms we see on Earth. Chlorophyll catalysts for converting carbon to food can resist
such high temperatures. A shadow biosphere with reversed DNA chirality is suggested by studies of
the Red Rain organism, whose DNA is undetected by standard methods but whose life cycles and
astrophysical signatures imply DNA capabilities. Physical and biological evidence in Figs. 10-15
support a biological big bang description of primordial life formation.
Part of the astrobiological processes that produce life in primordial planets is the distribution of
the templates or seeds of life by the plasma jets of the stars the planets produce, as well as the jets
from active galactic nuclei that devour millions of stars and eject to other galaxies trillions of life
infested planets and planet clumps. The biosphere and shadow biosphere therefore extend to all
material produced by the big bang, about 1080 planets. Biological processes are extremely efficient
at converting the carbon of planets to organic chemicals and their fossils, as we see on Earth. With
high probability, life did not begin on Earth, or on any of the 1018 planets of the Galaxy, but was
more likely brought to Earth and the Milky Way by cometary panspermia. Biology and medicine
are thus subsets of astrobiology on cosmic scales yet to be determined by future studies. |
