Here in England, our currency is the Great British Pound (£). Pounds are represented by an assortment of coins and bank notes. Each coin or note has a certain amount of value. For example, it is a fact that a £1 coin is less valuable than a £20 note. Both are more valuable than a fake £1 coin.
But from where does this value originate? Is it possible to determine the value of each coin/note, without referring to the fact the value is written on the coins/notes themselves? If we sent a sample of each unit to a lab, there are a lot of things that could be done to them. We could, for example, weigh each unit and place them in an order from lightest to heaviest.
But this would not result in each unit being placed in the correct order of value. Is there a scientific experiment that could? No, because value does not come from any objective trait. In the case of coins, value comes from design. A £20 note is not more valuable than a £1 coin because of any inherent trait of either unit, but because they were literally designed to have such value. Their value comes from their maker (mankind), not from their nature.
The same is true of life. Of its own nature, life has no value. Science can tell you a lot about life, it can't tell you if we should value it, how much we should value it, or why. For example, it is possible to say the human body will die if denied water for three or four days, but it is not possible to say we should care.
Just like money, life receives its value from its Creator. God created life, therefore God gets to dictate its value. And God has exercised that right, granting mankind a number of rights and responsibilities.
Evolutionists often think they can make a similar claim. They're often big on issues like conservation, preservation, and generally caring for the planet. And that's cool, it's great they're so passionate about it. They make a dog's dinner of it sometimes, but they're trying to fulfill the Dominion Mandate, just as Scripture says the Lord has driven them to do. But as good as it is to care for the planet, Evolutionists can't say why it's good to care for the planet. In their worldview, life is an accident. It has no purpose. We can have opinions on values, but those opinions are just that: Opinions. There is no room for objective value in an Evolutionist worldview.
Make no straw men, I am not arguing "life has value, therefore Evolution is not true because it necessarily denies that". I am, however, saying that Evolutionists typically cannot live consistently with their worldview. Most Evolutionists spend their lives behaving as if there is a God. Why not go the full 10 miles and get to know Him?
