When the Sun Touched the Earth

"John A. Eddy (Harvard -Smithsonian Center for Astrophysics and High Altitude Observatory in Boulder) and Aram A. Boornazian(a mathematician with S. Ross and Co. in Boston) have found evidence that the sun has been contracting about 0.1% per century…corresponding to a shrinkage rate of about 5 feet per hour." – Lubkin, Gloria B., Physics Today, V. 32, No. 9, 1979. http://physicstoday.scitation.org/doi/pdf/10.1063/1.2995728

If we take the diameter of the sun as close to one million miles and the rate of change of the solar radius has remained constant, 100 thousand years ago the sun would be twice the size it is now.

What can we say about the ability of life on earth to be found prior to 100 thousand years ago?  I would argue that even with 20 billion years after some accidental beginning, life could not have added the complexity required in the code of life to have any life, let alone in such abundance and variant. 

The results of a google search gave me dates for life beginning 3.8 billion years ago, but based on the rate at which the sun is shrinking, earth would have been inside of the sun only 20 million years ago. 

 My conclusion:   Life begin between 6-8 thousand years ago when it was spoken into existence.
