Aaron- thanks for your comments, but on this thread I'm less interested in the "poking holes in the OE theory" and more interested in hearing what scientific evidence would lead you to conclude that the earth is young.
I understand that, but if the Bible seems to indicate that the earth is no more than a few thousand years old, then poking holes in the old earth theory brings credibility to the BIble, as if it needed it.
Consider this, strictly from the Bible.....
Exodus 20:11
For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
He made ALL there is...in HEAVEN, in the EARTH, in the SEA...That includes stars, planets, moons, humans, etc. etc. etc. All this was in six days! It's in the context of resting on the seventh day after six days of work. If you consider the days of Genesis 1 different eras that were possibly millions of years, you'd have plants without the sun for millions of years and without insects to pollenate them. Plus you'd have Adam living partly through the sixth day and all the way through the seventh day making him possibly millions of years old before he died, contradicting Genesis 5:5 (he was 930 when he died).
If the Bible is not deceptive, God created the earth on day 1 - Adam less than a week later - and Adam died when he was 930 years old. Unless there are massive gaps in genealogies in the Bible, the earth could not possibly be more than a few thousand years old. I will admit there are probably gaps in the genealogies but not the size that we'd need to harmonize the Bible with what many scientists say about earth age.
Have you considered the magenetic field's decline. It has never been observed to increase in intensity worldwide, but they claim that is going through reversals. If you increase it backward through time at the rate it's decreasing now, the earth would have not been able to sustain life because of its intensity not even 100,000 years ago.
The earth is spinning at the equator at the rate of around 1000 mph, but it is slowing down at the rate of about one second per year. This is not a problem whatsoever if the earth is only 10,000 years old or so, but if it's billions of years old it would have been spinning out of control creating insane winds due to the Coreolis effect and unable to sustain life.
I know this argument must make some major assumptions. For instance - we don't know that the earth has always been slowing down at that rate, but it has been as long as they've been measuring it. But another person will use the speed of light and star distance as an argument for an Old Earth and we don't know that the speed of light has always been a constant.
There are simply gonna be some assumptions made on either side of the argument. The thing I feel most comfortable doing is, looking at the Bible to see if it indicates anything one way or another. It is my belief that it does and it is my belief that the evidence they find is consistent with a major catastrophe (the flood) and with a young earth.
