If things were different, they'd be different. We'd be different.
There are many formulations of the anthropic principle, and any number of exceptionally rigorous examinations of it, both supporting and opposing. Its an unresolved questions.
Your point about oxygen is completely incorrect though - in the last 300 million years, the oxygen content of the atmosphere has swung wildly, reaching above 35% and below 15%
And where do these numbers come from? And please don't just say science. How was this measurable? Which textbook or Popular Science Magazine was this quoted from? I'd really be impressed that a scientist would be able to empirically and unquestionably arrive at the conclusion that there were, in fact, variations in oxygen levels on earth! And how could they arrive at the fact it was 300 million years ago? Do you see how much faith has to go into a mere mortal man's estimations over what a deity, such as God, simply spoke into existence? I don't play the "what if" game or "if things were different game" because that's not fact. I'm talking about the Earth as we know it today and as it is and has been in order to sustain life since the beginning. So please, enlighten me. Where did this tidbit of information come from? How do we know it got as high as 35% and as little as 15%?
Apart from non-belief in deities, name an atheist dogma.
Namely that evolutionists would rather entertain goo, an alien egg, a big bang theory, or something else other than entertaining the
idea that there is intelligent design in everything around us. In DNA, in plants, in animals, in humans, etc. The more we learn about our surroundings, the more complicated we find it really is and it becomes harder and harder to believe that non-intelligence or matter simply composed everything and pieced everything together randomly. I don't care if you quote me 3 billion years or 300 billion years, non-intelligence did not randomly piece together life or organisms as we know it today. There's not a chance at all this happened. The fact remains that evolution cannot be replicated in a laboratory and it's because of these aforementioned reasons...and logic for that matter.
Isn't it funny how evolutionists want to assign an intelligence to something they deem non-intelligent? Example? The coined term "mother nature" is often used. Why is that?
Science is simply a search for causes. There are two types of causes:
Non-intelligent (Natural)
Intelligent
An evolutionist would believe that DNA happened by chance or through non-intelligence whereas any simple change in a sound pattern (such as the SETI program) is considered intelligent. Do you see the conflict of reasoning here? Do you see the fallacy in what is known today as "science?" Why the conflict of reasoning? Could it be because these things must happen in order to fit the limited worldview of the non-believer?
Finally, when did evolution become fact? I suppose if you say a lie long enough... Additionally, the reason for the zealousness of those like Richard Dawkins is because evolutionists/non-believers need to believe there is no God. With no God, who then can stand in the way of what you think is right or wrong? Moral relativism takes place and you become your own god. This is why you want to believe it...this is why you need to believe it. Who is God to tell you what is right or wrong? Am I right? So to answer your question, the overzealous belief in the
Theory of evolution has to be dogmatic. Otherwise, the opposite is true; which is there IS a God and you are not it. And maybe you don't think of yourself as a god, but your actions say otherwise. You'd rather believe you have control over your own destiny and control over things in life....until life strikes back...and God forbid a terminal illness happens, there are things that are out of your control. Yet there is a thought that the atheist would rather not entertain.....surrender. Self-surrender and humility that things are indeed out of your control and things you do not understand, yet there is a loving God who is merciful and promises the Great Comforter to us.
Now, another atheist replied to me saying that there are living organisms that use death to bring about life. They use this as a foundation for the fact that natural selection happens and death brings about life, which further reinforces the idea of mutation. But again, mutations are factually destructive. They're not PRODUCTIVE. In fact, 99.99% of mutations are destructive (I can't say 100% because that's just not science). So how could something chaotic bring about order and harmony? But Christians have an answer. The answer is God never intended for animals to kill each other or for any death to happen when He created the world in Genesis. When God created, it was good....in fact the Bible says, "...it was VERY good." God wished for his creation, man included, to simply have faith in God and obey Him so that all creation have eternal life with God. The Book of Revelations also says there will be a new creation here on Earth and everything will be the way it was always supposed to be. So yes, there are insects that cause death to bring life. Yes, there is fungi that destroys something to maintain its own self-preservation. But these consequences are a direct result of sin in the world. When sin entered the world, there was a great divide.
The divides are as follows:
1) Us vs. God - Adam and Eve literally walked with God and saw God. They talked to God! When sin happened, God expelled them from the garden of Eden and thus were divided away from God as a result of their sin.
2) Us vs. Others - Because of sin, Adam and Eve tainted relationships. We read later the consequences placed on women and on man as a result of their sin. We read in just a few chapters later, that the first murder happens within Adam and Eve's family! All of this....because of sin! Death (or natural selection as the evolutionists would have it) is a direct result of sin.
3) Us vs. Creation - Today we have hurricanes, floods, landslides, typhoons, earthquakes, tornadoes, etc. We also have violent animals, poisonous animals, and animals that need to be killed by other animals for life...for nourishment. Yet all of this was never in God's original design for creation. Death was never meant to be a part of His plan. Yet free will allowed sin to enter the world....so now we have Hawk Wasps laying eggs in Tarantulas, thus killing and destroying for its own species preservation.
4) Us vs. Us - We are in conflict with ourselves. We fight and toil with our inner emotions and demons to do right. When we serve ourselves in selfishness and self-centeredness, people will never be truly happy. You can have every material thing in the world and you still won't be satisfied. The sin we wrestle with within ourselves, is directly tied back to what happened in Genesis and what happened when sin entered the world.
