Origin of Life
My brother-in-law, a Structural
Engineer wrote this to me as he was puzzled how life came about.
“Aiyah, just wondering. Maybe
in a few million years from now, these organic molecules could coalesce, mutate
and go through a process to form life?”
My very, very brief answer to him
is:
These molecules could coalesce as
large and complex as they like, as long as they like to combine, but they are
still dead without any life in them, unless a living spirit (soul) is pumped
into them to make them alive just like a piece of beef is dead when taken off
from a living cow.
And the LORD God formed man of the
dust of the ground, and breathed into his nostrils the breath of life; and man
became a living soul (Genesis 2:7)

Origin of the Covid Virus
As far as expertise scientists in
evolutionary biology know, here is a very short summary how viruses and later
other higher organisms may have evolved:
Age of Earth and History of
Evolution of Life on Earth
1. 4,500 – 4,400 million years ago
(Mya). Accretion of Earth
2. 4,200 million years ago (Mya)
Atmosphere and oceans form
3. 4,000 million years ago (Mya)
Prebiotic chemistry became possible
4. 3,800 million years ago RNA
world shown by the first chemical fossil
available (viruses)
5. 3,600 million years ago the
first DNA protein life came into existence
6. 3,500 million years ago LUCA:
Archaea / Bacteria spilt and also
photosynthesis (autotrophy) began.
7. 2,700 – 1,900 million years ago
the first eukaryotes / sexual reproduction became possible.
8. 1,000 Mya?
9. 650 Mya Metazoans
10. 575 Oldest large organisms,
etc, etc over the billions of years.
It is clear that the viruses were
the first pre-life form between the living and non-living that may have come
into existence by random collisions of untold trillions upon trillions of
nucleic acids, plus nitrogen compounds such as amino acids synthesized by
lightning shown by Miller–Urey chemistry experiment
in 1952 that simulated the conditions thought at the time to be present in the
atmosphere of the early prebiotic Earth, in order to test the
hypothesis of the chemical origin of life under those conditions. The
experiment used water (H2O), methane (CH4), ammonia (NH3),
hydrogen (H2), and an electric arc (the latter simulating
hypothesized lightning).
These primordial chemicals of
life may have been floating in the warm primordial oceans
where the first life arose. But what we do not know is, how did the
bacteria and other higher organisms come into existence on their own with the
viruses going in between the living and non-living?
There are many theories on life's
origin, among them they came from the hot vents in oceans floors. We shall not
go into them as they would run into lengthy chapters and piles of conference
papers already being presented at symposia.
Suffice to say that even though
viruses need a living host such as an animal for their duplication, it is also
possible for them to mutate randomly on their own to give rise to other kinds
of viruses including the coronaviruses like the present Covid virus. It is not
necessarily that they must originate from the SARS-COV-2 strains as some
scientists believe just because their RNA showed similar sequences.
In truth we really do not know how
this Covid virus came into being despite the US blaming China for creating this
virus, or from a leak from Wuhan Institute of Virology among other theories
such as they came from wildlife like bats and pangolins sold in Wuhan markets. It
may have originated through multiple mutations from other viruses over millions
of years into SARS-related coronaviruses.
It could also be seeded onto Earth
by passing comets from icy planetesimals in the Oort Cloud surrounding the Sun
2, 000 to 200,000 astronomical units away.
(1 astronomical unit = 1.58 light
years or 14,959,7871 km)
We can only answer this if we bring
in what the Hebrew Bible tells us.
"Behold, saith the Lord, I
will bring plagues upon the world, the sword, famine, death, and destruction.
For wickedness hath exceedingly
polluted the whole earth, and their hurtful works are fulfilled". (4 Ezra
15
:5 - 6).
It is the Intelligent Designer
prerogative to do anything He wishes, and, in any design, He likes to this
Earth.

You have put your postdoctoral qualification from Cambridge on the evolution of life in good use for others like myself to undersand. Congratulations
