because by changing only 1 variable and keeping everything else the same allows you to see how the cause (that 1 changed variable) creates a new effect.

think of it as a math problem:

2x, where x represents our independent variable

if x=3, then we know that 2(3)=6

but if x=5, hten we know that 2(5)=10

you can then see the relationship between both problems and how that change affects the outcome.

i hope this helped!

An independent variable by definition is not directly related to any other variable in the equation or formula. By changing just this one variable and observing the result, one may learn how the whole is affected by this one variable. If you were to change more than one, any change seen would be harder to attribute to one variable or the other.

Think of a recipe for a cake.

Christians ought better to be employed in the good news of our Creator …stepping into our very shoes rather than setting up a laboratory to prove Himself or draw evolutionary diagrams,.He actually identified with our real concerns and problems.Very few people care about contemplating their navel, more about their own happiness , safety and destiny. If He had told us we were the product of chance and probability I don’t think that would have answered our deepest needs , do you? Who tries to disprove evolution? Certainly the majority must accept a proven capacity for mutation within species ,otherwise they would become extinct under environmental change. Even though I and many more sensible people including the majority of scientists are not persuaded about “Genetic Evolution” that doesn’t totally discount popular theory or opinion. Darwin and the neo Darwinists of today simply have had an impossible problem with the complete dearth of inter species proof.So to project a fraction of human of experimentation onto a multi billion year canvass of their own invention seems a giant step of Faith in their own devices. Without trawling through the whole of your red herrings (sic) I think if we spent more time reading about the incredible correlation between Scriptural revelation and the course of history you would have proof enough that everything ,including the whole cosmos is moving inexorably according to a predetermined climax. Let us therefore concentrate on the only burning issue of the day:- Not the ” Big Bang” of the past but the glorious ” Big Bang” not so far away from us. Maybe black or white hole, what difference?
