Correct! Their lineages split about 50 million years ago.Actually seals are more closely related to dogs than they are cats

And there are many other Decaying Isotopes to use for various age samples.Answers to Creationist Attacks on Carbon-14 Dating
Answers are on the net
Question: A sample that is more than fifty thousand years old shouldn't have any measurable C-14. Coal, oil, and natural gas are supposed to be millions of years old; yet creationists say that some of them contain measurable amounts of C-14, enough to give them C-14 ages in the tens of thousands of years. How do you explain this?
Answer: Very simply. Radiocarbon dating doesn't work well on objects much older than twenty thousand years, because such objects have so little C-14 left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium-40 (K-40) decay. Younger objects can easily be dated, because they still emit plenty of beta radiation, enough to be measured after the background radiation has been subtracted out of the total beta radiation. However, in either case, the background beta radiation has to be compensated for, and, in the older objects, the amount of C-14 they have left is less than the margin of error in measuring background radiation. As Hurley points out:
Without rather special developmental work, it is not generally practicable to measure ages in excess of about twenty thousand years, because the radioactivity of the carbon becomes so slight that it is difficult to get an accurate measurement above background radiation. (p. 108)
Cosmic rays form beta radiation all the time; this is the radiation that turns N-14 to C-14 in the first place. K-40 decay also forms plenty of beta radiation. Stearns, Carroll, and Clark point out that ". . . this isotope [K-40] accounts for a large part of the normal background radiation that can be detected on the earth's surface" (p. 84). This radiation cannot be totally eliminated from the laboratory, so one could probably get a "radiocarbon" date of fifty thousand years from a pure carbon-free piece of tin. However, you now know why this fact doesn't at all invalidate radiocarbon dates of objects younger than twenty thousand years and is certainly no evidence for the notion that coals and oils might be no older than fifty thousand years.
>>@Syriusly: A sample that is more than fifty thousand years old shouldn't have any measurable C-14.<<
The answers are NOT on the net. As usual, atheists are wrong. It is circular reasoning.
We can lead a christo-creation cultist to the facts- but I can't make you read the facts.
You will instead of course embrace cristo-creation cultist falsehoods- because it is all a matter of faith to you.

Of course but the christo-creationists will always whine 'but carbon 14!'
Why do you accept what he posted? He just discussed different techniques for dating. It doesn't mean they're true nor the methodology based on their assumptions is correct. It could be wildly incorrect. Which method can one use to date rocks that have been underwater for years? What method does one use to date objects/fossils in sedimentary layers?
YOU HAVE NO ANSWERS!!!
If we evolved from monkeys why are there still monkeys?????
If we evolved from monkeys why are there still monkeys?????
I don't....Why do you think that we evolved from monkeys?
My eight-year-old asked me that once. I explained it to her. Now she understands.If we evolved from monkeys why are there still monkeys?????
8 year olds are gullible by nature.....My eight-year-old asked me that once. I explained it to her. Now she understands
But lifelong scientists are not. And all of them and many 8 year olds grasp a concept that you don't.8 year olds are gullible by nature.....My eight-year-old asked me that once. I explained it to her. Now she understands
So you think you and your family evolved from monkeys? Fine knock yourself out....my family did not...But lifelong scientists are not. And all of them and many 8 year olds grasp a concept that you don't
No, and neither do scientists. But it is indeed a fact that chimps and humans share a common ancestor that lived about 7 million years ago.So you think you and your family evolved from monkeys?
When you find the missing link you be sure to let me know....okay?No, and neither do scientists. But it is indeed a fact that chimps and humans share a common ancestor that lived about 7 million years ago
Your statement belies a deep ignorance of the theory of evolution. There have been found several "missing links" between this most recent common ancestor and modern humans. Nobody with knowledge of evolution would make such a silly statement. Given your apparently vast ignorance of this material, I suggest you start with a very basic, beginner's primer.When you find the missing link you be sure to let me know....okay?
That's ridiculous nonsense....Your statement belies a deep ignorance of the theory of evolution.

Which part? Use your big boy words.That's ridiculous nonsense....Your statement belies a deep ignorance of the theory of evolution.

Given your apparently vast ignorance of this material, I suggest you start with a very basic, beginner's primer
Your whole post....if we evolved from monkeys we would have found the evidence by now....its more likely we came from another planet than evolved from monkeys....nonsense!!!! Like I said when you find the missing link call me....until then stop lying and misleading your kin.....Which part? Use your big boy words
Again, we did not evolve from monkeys. But we did evolve from primates, and we have found mountains of evidence of this. You confuse your abject ignorance of the existence of this evidence with the idea that none has been found.if we evolved from monkeys we would have found the evidence by now..
If we evolved from monkeys why are there still monkeys?????
