Well, actually, the age of the earth is not a Doctrine.
Rmmm... Well, it's always been for me. I always accepted it as taught to be 6000 years old.
The general age comes from adding up all the ages listed in the Scripture.
Yep, well, the list is somewhat incomplete in my mind. Did you check out that site I listed at the bottom of my post? The first slide and the following five slides should explain my concerns.
I do feel that GOD created an established ecological system during a 6 day period.
And that might be more feasible to me if God had started by creating the sun and the moon first before he used the illustration of evening and morning instead of in Genesis 1:16. If there were no sun and no moon, then how can evening and morning describe the passage of daylight which we rely upon to tell us when our days are ended and when they begin? It seems to me that evening and morning refer to something different than our conventional dusk and dawn. Without the waxing and waning of light brought by the moon and the sun, evening and morning could be used to describe any length of time.
The Creationist would understand that Adam very likely appeared as a thirty year old man at the time of his creation.
That may be how God created him... But it doesn't say in the Bible that Adam appeared to be a 30 year-old when he was created.
The Creationist would have no problem with the concept that Adam's age may only represent those years he lived AFTER he sinned.
I've heard this suggested too, but in Genesis 5:3-5 it explicitly tells us how long Adam lived and gives us no reason to believe that the text is metaphorical in nature or varying from conventional standards in meaning.
Could Adam theoretically have existed on the perfect earth in a perfect garden for several hundred or thousand years prior to his fall?
I believe it's possible, but given my understanding of Genesis 5:3-5 I don't believe it to be probable.
This is certainly a possibility, but that does not aid evolutionism. The Creationist understands variety and accepts changes brought on by the FALL of man and changes that happened as a result of the FLOOD.
I'm not completely for or against evolution. As far as I'm concerned, we know
who created life - we just don't know
how He did it.
The Creationist does NOT accept survival of the fittest concept of evolution.
Do you mean natural selection? If so, I accept that view. Happens all the time in my opinion. Some animal living up north - for some reason - grows longer or thicker fur than another of its kind (we're all different and our bodies vary). It is allowed to mate before it dies because it is more fit to survive. The other animal with shorter or sparser fur would be forced to migrate southward or die. If it migrated southward, then its descendants would - through natural selection - sooner or later adapt to their environment or migrate in various other directions in order to survive.
The Creationist does not believe dogs and cats had the very same ancestors. Creationists do not consider humans as animals.
I agree with the last part. Although, we are the ones classifying what living organism is a human and what organism is an animal, save for God's original differentiation of humans & animals in Genesis. We're all flesh and blood. I, personally, don't know if animals are spirits as humans are and just are clothed with tissue. In fact, I don't even know what a spirit is exactly. If you can refer me to passages in Scripture that might explain what a spirit is, then that'd help. As for the cats & dogs thing, I really don't know what to believe. I'm not a genetic engineer, and I don't know whether it's possible or not.
