silliness, survive = reproduce
those that survive to reproduce are the 'fittest'
those that survive to reproduce are the 'fittest'
Your attempt to salvage the tautology conundrum of evolutionists is in itself an exercise in futility. If you insist on changing the definition of "survive" to mean "reproduce," you are required to apply the definition uniformly, not selectively to one side of the equation.
Thus, "The survival = those who survive to reproduce, of the fittest = those who survive to reproduce."
The absurdity of the tautology is not mitigated: "Those who survive to reproduce are those who survive to reproduce."
One day, when this life has run its course, we will all stand before the One whose existence and creative work shall be denied no more. In that hour the atheistic fantasy that everything we know is the result of blind chance will evaporate as so much ash and smoke.
