I assert that life is not a random process nor is it planned out according to a recipe. The world is neither a biscuit bakery nor an auto factory. Those kinds of things are human creations as they are also parts of the universe. We are each different. We none of us are universal-standard engineered machined parts from an assembly line. We are not little globs of dough from a bowl baked in temperature controlled ovens. Those kinds of things are human creations. That is obvious.
And no two biscuits based on the same recipe are the same nor are even two engineer-universal-standard auto parts quite the same. There is the simple fact of variation however small. Measurement is not exact it seems. No one was there to measure out the material used to make us. Even if there were then that measuring person could not make the precise same measure each time. That is an observation not inborn in us but figured out from our common human historical experience.
The biscuit or car that becomes after the baking or assembly line is at least slightly different from any and every other just as every person is different. If you ever worked in a quality control part of a factory you would be aware that even the most accurate of measurements ends up in endless variations. Some end results are inexplicably very different though often enough successful results none the less. Most cars run and most biscuits are edible. Many are tossed out as being too different, not up to some standard or other, or some other reason. We as human beings do that too to human beings.
Even if we should not do that with human beings we as human beings do. The anti-evolutionists would kill and non-create the already created. The anti-abortionists would kill and abort the already born. And the believers in one sort of things kill the believers in other sorts of things. Human beings are killers. We are predatory, nasty, vicious, violent, raging, biting, scratching, back-stabbing, and rip-it-apart creatures. We are not just fighters. We are killers.
Simply put: “We are here and grow and this demonstrates our necessary being”. If we did not exist who then is reading this? “I” therefore I am. But the phrase “necessary being” is used by some to mean that “we” have to be here by some guarantee built into the universe. This is a useless argument, I think. We are and that is sufficient. We are and that is necessary or else, well, there would be no “we”. Isn’t that complete?
