Single layer of sediment? Why?
Because floods leave layers of sediment behind as evidence that they occurred.
In response...how do you explain oil and coal deposits globally that are clearly the result of sedimentary burial of plants and animals?
Oil: because in the deep past, organic matter from sea life and plants accumulated on the sea-bed over LARGE periods and eventually got burried. Over many millions of years of being trapped under high pressure, those organic materials turned into the oil we drill up today.
Coal: trees and plants that lived hundreds of millions of years ago in swampy forrests that got burried by layers of rock and dirt. The resulting pressure turned those planets and trees into coal over the millions of years that followed.
Why should there be a genetic bottleneck?
Because when you reduce the population of size of a species to several hundreds (let alone 2 to 14) individuals, there is an extreme loss of genetic diversity, which is what a genetic bottleneck is.
When species do not have a genetic bottleneck, it means the species population size was never greatly reduced.
Actually if the earth was billions of years old, genetic degradation would he the problem, not bottleneck for YEC. I think loss of DNA information is a far bigger problem.
This is a statement rooted in absurdity and ignorance. It makes no sense whatsoever in context of how genetics actually works.
Explain climate change...
Dramatic increase of heat trapping gasses in atmosphere => warmer atmosphere => climate change
clearly we are making it worse and not better.
Unfortunately, yes.
Although scientists seem to have finally succeeded in raising awareness that it is at least happening and that we need to change our ways. Unfortunately so far it seems like a lot of talk and very little action.
despite the evolutionary inference survival of the fittest suggesting it should improve...
No idea what that is supposed to mean. Sounds like another statement rooted in ignorance and absurdity.
oh that's right, it's not survival of the fittest, it's just a random cycle that will eventually wipe itself out and start over!
And another one of such statements.
Billions of metres of water???
The bible says specifically " the fountains of the deep burst forth"
That's indeed what it says. Off course, there are no such "fountains" nore is there any evidence there ever were.
Are you able to.prove that there are is such thing as underground aquifers and that before the flood those aquifers were significantly different to what they are today?
That would be the job of those who claim the bible flood happened. Don't ask us to do your homework. You make claims, you support them.
Icecaps, if they all melted, by how much would sea levels rise...is it not in excess of 70metres?
I don't know without looking it up. But it stands to reason that if all ice melts, that sea levels would rise, yes.
Can you.prove that all mountains 4500 years ago were as high as they are today...given Geology clearly shows historical uplift which is actually consistent with biblical claims rather than contrary to it!
Geological uplift doesn't happen overnight. To get the geological uplif at a rate that your story would require, would be so catastrophic that it would boil the world killing everything, including those on the magical boat. The world would be a barren place devoid of life if such would have occured.
We know the deepest part of current ocean (challenger deep if memory serves) is approx 11,000metres....thats 11km. Are you measuring your start elevation from sea level or the ocean floor 11km below sea level?
Mountains grow through geological uplift by a few milimeters per year.
You are dog barking up trees given the depth of the ocean shows exactly where all the water was...and still is! Its not the water volume that is the problem here...its only an argument about average land elevation above the ocean floor!
Your argument requires an uplift at a rate that would be completely cataclysmic and for which no geological processes are known to even be possible.
Clearly you have no idea about the physics involved.
People have no idea because they look at what is visible above the surface of the water and not how deep our current oceans are today.
Right, right. Scientists don't look at oceans at all, only at land.
Do you really believe this?
This is a zero problem for YEC and those who believe in Noah's flood.
The only reason YECs don't have problems (or better put: don't realize they have problems), is because they don't care about evidence.
