Flooding leaves tell-tale signs in the geologic record.
- Boatbuilding: the boat simply cannot hold itself together, especially not for an entire year at sea, where issues such as weathering become a concern as well.
Supernatural flood, supernatural water.
- Altitude: "highest mountaintops"? That puts it in the so-called "dead zone", where there simply isn't enough oxygen, and the temperatures are far too low to be survivable. Unless you want to claim that the highest mountaintops were somehow considerably lower before the flood, which not only would require a rate of sediment deposition that is completely unheard of, but also presents problems in terms of mechanisms, i.e. "how did this happen".
The "Dead Zone" concept has been abandoned. No such thing.
- Food: after being underwater for a year, all land plants on earth would be completely dead. While some might recover from seedlings, the fact is that anything left on earth at that point would starve to death.
Silt found after a flood is very fertile. Some farmers depend on it.
- Feeding: what did the lions eat? How did Noah keep literally tons of meat from spoiling? What of the animals with specialized diets?
God put them on the Ark. Many would naturally hibernate. Likely they all naturally or supernaturally hibernated.
- Transportation: how did the 3-toed sloth get from Mount Ararat to South America? Why don't we find any sloth corpses or fossils in the intervening sections of land? How about the Koala, which had to cross all of Asia and the ocean between mainland asia and Australia, and only feeds on a plant that only exists in Australia (which wouldn't have survived being under miles of water either)? And why can't we find any remnants of these animals making this trip?
A pumice raft is a floating raft of pumice occasionally created by ocean-based or near-ocean volcanic activity.
Biologists suggest that animals and plants have migrated from island to island on pumice rafts.[1][2] Astrobiologists have hypothetically linked pumice rafts to the origin of life.[3] A large pumice raft appeared near New Zealand in August of 2012. It was reported to be 300 miles (480 km) long, 30 miles (48 km) wide, and riding two feet above the surface.[4] On 10 August 2012 a raft with an estimated area of 10,000 sq miles was observed near Raoul Island, north-east of New Zealand by the Royal New Zealand Navy.[5][6][7]
- Spatial Geometry: how the heck do you fit so many species onto such a small boat? It's understandable that the authors of genesis knew nothing about the variations found on earth, but the fact is that there are upwards of a million known extant species of animals; estimates place the total number as high as 50 million. And never mind the food storage, and the fact that many of them have very specific diets, and the waste removal.
Hibernating turtles don't even breath. Only certain classes of species are listed in scripture. Stick to the data.
- Parasites: what about all the various pathogens and parasites? Did Noah and his family share all of them between them?
That would be a mean trick to play on Noah. Complaint excused.
- Genetics: two of any given species is the kind of incredible genetic bottleneck that we should be able to detect in the genome. In fact, we can find bottlenecks going back considerably farther than Noah's flood (which really shouldn't be visible if the entire population was then later reduced to two). Why is the genetic diversity of the dog so much greater than that of the Cheetah?
Because people feed dogs.
- Anthropology: how did we go from a global flood to countless massive civilizations, in a handful of generations of 8 people interbreeding? In fact, we have evidence of human civilization during the alleged timeframe of the flood, and they didn't seem particularly bothered by it.
I don't buy into anyone's aledged "timeframes."
- Marine life: how exactly did fish survive the global flood? Was the flood salt- or fresh-water? Either way, we're looking at the extinction of all fish who rely on a saltwater/freshwater environment, and the Salmon are just totally screwed either way. Same with most kinds of marine plant life.
In the movies, The Flood is very dramatic! In scripture....there is no turbulence, wind or waves, of any kind except for "the fountains of the deep" which would be pretty spread out even if there were more than a handful.
Because of characteristic differences between salt and fresh water, however, the two don't always easily blend. Sometimes they don't mix at all, but instead stratify or form layers.
- Physics: where did the water come from? Where did it go? How did it lift the Ark without destroying it?
If we think the mountains lower or the oceans shallower than today, then the amount of water on the earth now is perfect.
And that's just off the top of my head, as a complete layman. I'm sure there are other sources that can go into far more detail and far more points. And I'm sure that you and other creationists can come up with bad ad-hoc explanations for these - explanations which, like the hydroplate theory, are completely untenable and cause more problems than they solve. They're never well-thought-out, almost never provide any real evidence for their claims. It's always "here's what we know, find evidence to support it", never "here's the evidence, what does it support?".And remember, the moment you invoke a "miracle" or "divine providence", you've lost. You've given up.
Lol....you forgot....
you are the one reading the Bible dude. What's the #1 rule of science?
Don't MESS with the data.
So. Here's
the data, just on water, you have in your hand.
WATER TURNED TO BLOOD—
Water everywhere became
BLOOD. The
fish died, and the river stank. (
Exodus 7:14-25)
RED SEA DIVIDED (Ex. 14:21-31)
DRINKING WATER FIXED—(Ex. 15:23-25)
WATER from the rock at Rephidim (Ex. 17:5-7)
WATER PROVIDED IN DESERT—from the rock, after smitten twice by Moses (Num. 20:7-11)
HAILSTORM destroys the Amorite army in a battle with Joshua (Josh. 10:12-14)
WATER from a hollow place “that is in Lehi” (Judg. 15:19)
THUNDERSTORM causes a panic among the Philistines at Eben-ezer (1 Sam. 7:10-12)
THUNDER and RAIN in harvest at Gilgal (1 Sam. 12:18)
RAIN—in clear response to prophet Elijah’s prayers (1 Kings 18:41-45)
RIVER DIVIDED—Jordan divided by Elijah and Elisha near Jericho (2 Kings 2:7, 8, 14)
WATERS OF JERICHO HEALED by Elisha’s casting salt into them (2 Kings 2:21, 22)
WATER PROVIDED for
Jehoshaphat and his
allied army (
2 Kings 3:16-20)—“Ye shall not see wind, neither shall ye see rain; yet that valley shall be filled with water, that ye may drink, both ye, and your cattle, and your beasts.”
JONAH SURVIVED IN THE FISH’S BELLY and safely landed (Jonah 2:1-10)
FISH—the miraculous draught of fishes (Luke 5:4-11)
WATER TURNED TO
WINE (
John 2:1-11)
FISH—draught of
fishes instantly caught at Christ’s instruction (
John 21:1-14)
SEA STORM STILLED ON COMMAND (
Matt 8:23;
Mark 4:37;
Luke 8:22)
JESUS WALKS ON SEA (
Matt 14:25;
Mark 6:48;
John 6:15)
So this is the data you have on water. Deal with the properties of water, the reality of the data you have.
You've made it clear that the scientific evidence we have does not point to a flood. If you can invoke magic to explain away an unfortunate part of your theory, there is literally not a single hypothesis in existence that you could not validate in that way. And if you have to invoke magic, it's clear that your hypothesis is nonsense.
What I really want to impart here the most is how frustrating this is. It is the 21st century. We understand more about the universe around us than we ever have before. The fact that you can post on this forum means that you have access to as much knowledge as you care to find. And yet, we still have intelligent, thoughtful people who think that 4,000 years ago, a man built a boat, put two of every animal on earth on it, and then a supernatural entity flooded the entire world. It's ridiculous. This is not the kind of thing we still need to be debating! Not when it was settled and laid to rest more than 200 years ago!
