So... I was called all kinds of names by a fundamentalist lately because I believe in science and therefore don't think the Earth is less than 6,000 years old. I was even challenged to a public dialogue. So given that I'm someone who never passes up an opportunity to show up science as superior to creationism, I rise to the challenge.
But I'm not a bigot. I won't call people names if they don't believe in science. I simply do believe in science.
Here are reasons why I think the Earth is older than 6,000 years old:
Age of the Earth, 4.5 billion years old: How Old is the Earth: Scientific Age of the Earth
Age of the Grand Canyon, 2 billion years old: Grand Canyon National Park - Frequently Asked Questions (U.S. National Park Service)
Triceritops skull found, 67 million years old: 03.06.2006 - Smallest Triceratops skull described
Oldest human skull found, 160,000 years old: Dawn of human race uncovered - life - 11 June 2003 - New Scientist
That list only took me five minutes to research on the Internet. But any High School science teacher can tell you a few other things that don't make sense about Creation story in the Bible:
1. The human race would have died out from inbreeding if Adam and Eve were the first two humans and were the only humans on Earth at that time.
2. There is ZERO evidence that an Extinction Level Event occurred that matches up with the Great Flood (granted, several cultures have holy texts that mention a deluge, but the whole world never flooded everywhere at the same time, and certainly not for 40 days).
3. Snakes do not talk.
4. Shrubs do not talk.
5. Donkeys do not talk.
6. Walls do not self-graffiti.
7. The Earth is also not flat.
8. The sky is not a hemispherical dome.
9. There is no such thing as an "unclean" animal (although some are not good to eat, and some produce poison or venom).
10. A woman is not more "unclean" after giving birth to a baby girl than if she gives birth to a baby boy.
11. Once someone is dead for more than 8 minutes, they generally remain dead.
12. Homosexuality occurs in nature.
13. Prayers don't cure diseases, medicine does.
14. You can't fit the entire ecology of the Earth into a single cargo ship.
15. Human males aren't missing ribs.
I'm happy to hear reasons why someone might think that the Earth is only 6,000 years old. I promise not to call anyone any bad names. If you believe in something else entirely, I'm happy to hear what that is too.
My own belief is this: We live in a universe that is regulated by physical laws. The universe is very large and very old. There may be other universes as well. I think there is a Higher Power, but that entity is not the highly limited, vengeful, psychopath of the Old Testament. I think that the universal deity primarily has a "hands off" policy and may occasionally nudge evolution in one direction or another -- but that's about it. I think that the universal deity is interested in the universe being filled with life, but is distinctly uninterested in what shoes we buy, who we sleep with, or who we vote for, or how (or even if) that entity is worshiped or affirmed.
