Evo scientists contend that life began 3.8 billion years ago possibly around vents in the bottom of earth's oceans. According to this theory, life began when the first replicating molecules and cells appeared in or aroud these vents. Accordingly, this process is not now going on. It was an anomoly--a one time event?
If the previous conclusion is true, curent cells in all life forms (including humans) must contain unscathed copies of this original genetic material--a copy of a copy duplicated for 3.8 billion years (that's what constitutes life) . Incredible.
The human begins with one cell. At maturity the human body consists of 100 trillion cells. Moreover, the 100 trillion cells are replaced totally every ten years--with some cells living longer than others. When someone is 50 years old there have been over 500 trillion copies of their orginal one cell.
One theory of the cause of death says that copying errors occurring in cells eventually (genetic entropy) causes death.
3.8 billion years of genetic entropy would most assuredly have doomed life by now!
That leads to the conclusion that life on earth hasn't been here that long.

Unscathed? Wow, you really don't understand evolution.
Here's a question for bonus credit, Mike: If "genetic entropy" causes ageing and death, explain these two phenomena:
1. Biologically immortal organisms which only die when they are killed (such as hydra and some jellyfish)
"Goddidit" will not be an accepted answer.
Oh, and that cell thing... It's a myth. Snopes or Wikipedia it.

Sure it's still happening. But there's generally something around to eat anything organic that forms before it gets very far along nowadays. There wasn't anything to eat it then.
Accordingly, this process is not now going on.
Who says? It could be. It's just that now there are more advanced things that will eat you as soon as you're formed - a problem not faced by the first replicating cells.

Sure. There are some things that are found in virtually every form of life on the planet. How did they get faithfully duplicated for billions of years? Because anything that didn't have a true copy immediately died.

Except for eggs. A girl is born with the cells for all the eggs she'll ever have in her life. The only time they get duplicated is during fetal development of her daughters. And if there's a serious duplication error, the egg never develops into a child.

It has. Over and over.
"If the previous conclusion is true, curent cells in all life forms (including humans) must contain unscathed copies of this original genetic material--a copy of a copy duplicated for 3.8 billion years (that's what constitutes life) . Incredible."
Incredible, indeed. That is, your contentions are without credit.
Fine. Now go on to prove that God, as described in the Bible, exists. How do you know that we weren't seeded here by aliens, or by some sort of Galactus-type super-being? There is as much evidence for that as for God.
Well, at least he’s closer than that old fart going on about peanut butter, but a miss is as good as a mile, as the saying goes. He’s still wrong.

Above is a picture of a hydrothermal vent, also called a 'black smoker', surrounded by various corals and tube worms and crustaceans and fish and the like. They are home to some of the most diverse and lively ecosystems on planet Earth. These things exist today, ignoring your cell duplication bullshit, why wouldn't something similar to this happen when life began and continue happening due to the richness of the environment?
The human, and most other animals, begins with an egg-cell and a sperm-cell. Each conception is a mixture of two different sets of DNA's, it's not the same copies over and over again.
You didn't really pay attention in Biology classes, did you?

Maybe. The main difference between the prebiotic earth and after the emergence of life, is that there is now life that feeds on the stuff that could have been used in the emergence of life, and turns it into fecal matter.

Incredible indeed. No copy is 'unscathed'. Mutations happen all the time. The original is lost to time, and nothing can recreate it again.

What is this 'genetic entropy'? Your preconceived idea that a copy is always worse than the original? Not so in biology. Study a bit more evolution, then return here.
The human begins with one cell.
Wrong. As Swede already pointed out, every human being begins with two cells, one egg and one sperm.
So if you couldn’t get even that right, why should we listen to anything you have to say about biology?
"One theory of the cause of death says that copying errors occurring in cells eventually (genetic entropy) causes death. "
Another theory of the cause of death says that telomeres get too short. We have tested this theory by artificially lengthening telomeres. The organism lived a long time.
"3.8 billion years of genetic entropy would most assuredly have doomed life by now! "
Except 3.8 billion years of evolution has most assuredly preserved live to the present!

Only if you assume that there was only one cell that replicated throughout that 3.8 billion years. However, since you fail to consider evolution and genetic change, you've accidentally made an argument for evolution since there's no way life could continue without it.
"If the previous conclusion is true, curent cells in all life forms (including humans) must contain unscathed copies of this original genetic material"
Wrong... Copying errors can lead to improvements to the original.
Of course, the fact that the vast majority of copying errors are just Duplications, the "error" makes no fucking difference.
"Incredible."
Yeah... fucking incredible how much you need to ignore to make your point.
things change over time , so the first cell is likely to have ceased to exist in only a few years.
One theory of death is that the code in the cell shortens each time the cell replicates. When the code is exhausted then the cell dies without replicating. (telomeres ?)
You really don't understand the first thing about evolution or cellular biology? We don't expect the genetic composition of populatiosn to remain unchanged over thousands of years--as you point out, multiple natural mechanisms are known to act, and to introduce changes into genomes over time.
recall natural selection acts to conserve changes that increase fitness and to cull those that decrease fitness relative to a specific environment. We'd therefore expect that 3.8 billion years of 'genetic entropy', as you put it, wouldn't result in life being doomed, but in living populations becoming gentically and phenotypically diverse.
Which is exactly what we find today.
"If the previous conclusion is true, curent cells in all life forms (including humans) must contain unscathed copies of this original genetic material"
If they were unscathed, we would still be unicelular beings.
"3.8 billion years of genetic entropy would most assuredly have doomed life by now!"
How? It's not like the entire genome can succumb to entropy, it's maintained by the need for an organism to survive long enough to reproduce.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
