Correction:
The perception that TToE theorizes about the origin of life is being intentionally promogulated by people who cannot reasonably be assumed to not know better.
Is that what happened, when the primordial soup got zapped, lol?
Evolution, the theory is called, more properly "The Origin of Species." That was Darwin's title.
Evolution requires change over a period of time. Time then, by deductive reasoning must also have a beginning.
The origin of life is essential to the theory of Evolution.
(Man did not come from apes... Man supposedly came from a common ancestor - the "missing link" Louis Leaky searched Olduvai Gorge 30 years in vain for...)
The singularity of all life is the DNA molecule. All living things have it. Like the singularity of the "big bang" theory, you make the inadvertent admission life is some sort of immaculate conception.
The flaw in your logic is that life did not come from the earth, because the earth came from somewhere else as well. Life came from somewhere else... There is no more evidence that any species evolved here on the earth than there is evidence it was delivered or engineered by extraterrestrials.
