The question is how old is the Earth. The decision I have reached is 4.5 billion years old.
Uninformed? The figure comes from the elite of geological experts. That's why I believe it. It's not about debate it's about knowing stuff. I am not going to deny the figure experts have provided to me out of sheer stubbornness just because I can have a debate if I deny it.
I feel that with so many geologists on Earth, there will be quite a few geologists who have looked into the age of the Earth and this is the value they are providing.
I don't need to determine that. The fact that the figure provided by these fine geological organizations (eg US geological survey) is 4.5 billion plus or minus a few % tells me everything I need to know. Obviously they are convinced by the data, evidence and replication. Therefore so too am I.
You have already botched and you don't even know it. Scientists in fact have not calculated the age of the earth. They "accept" that it is at least 4.5 billion years old but that is a minimum figure not plus or minus a few %. No it's not a minimum figure. It's the age experts think the earth is within such a range of error. I believe it is 4.5 billion years old because that's what experts say on the matter. I thought your point was that I shouldn't believe the experts. |

The Experts used to agree that tetonic plate shifting was impossible. Somehow....that changed. So much for expert opinion. Remember how the feller that thought of plate movement was ostracized? The reason many experts did not believe it is that there was no good proposed mechanism to explain how plates could move at the time. Sometimes people are wrong for the right reasons. That was one of those occasions. www.aquaticape.org/wegener.htmlIf I was back then I would have accepted the consensus. I would have turned out wrong in that instance, but over the long haul my strategy of accepting the consensus will have more wins than losses. What I am disagreeing with on this thread is how people are giving too much weight to single expert backed theories, and conversely at subtracting too much weight from consensus opinions when just a handful of experts disagree. |

The reason many experts did not believe it is that there was no good proposed mechanism to explain how plates could move at the time. But that is the problem. There was evidence to support the concept even though no mechanism was known. So instead of saying he was probably right and more study was needed to find the mechanism, they just dismissed him as being wrong. Many times the truth is discarded in favor of the accepted consensus. Science is supposed to be about thought and exploration not fitting into the crowd. |

No it's not a minimum figure. It's the age experts think the earth is within such a range of error. You mean its the age your experts think the earth is and what is the range of error Socold. . . .how far does it extend? |

It's 4.5 billion plus or minus a few %. There is obviously an upper bound determined or they would say that was an upper limit not a precise value. |

So you don't know if the error range is one billion years or twenty billion years huh? Yet you just blabber blabber blabber blabber like some expert told you the secret of life. LOL! |

A few % means it is going to be a few hundred million years at most.
4.5 billion +- a few hundred million. Not billions.
