How old is planet Earth?

  1. Mar 11, 2008 #1
    :rolleyes: I've been wondering about the Earth's age. Some says...1000000000000 or what..? other says..almost 7000 years or 6000+..Well, what do you think?

    Well, we don't really know but an educated guess would be about 4.55 billion years (4,550,000,000). That's the calculated age from radioactive decay processes of some meteorietes. The oldest know rock from the moon is calculated to be 4.5 billion years. The oldest rock on Earth is 4.4 billion years old.

    Forget 6000, that's not science but misplaced faith.

    The age of the earth does not depend on what one personally thinks. The established figure is ~4.6 billion years and we know it from several independent lines of evidence.

    Really, it's most definitely older than 6000 years; we have evidence of human culture even from long before then in the form of cave paintings. (And of course, suggesting that those caves were created *with* the paintings opens up the door for Last Thursdayism as a counter-point....)

    I don't think anyone has ever said that the earth was a trillion years old.
  7. Mar 17, 2008 #6
    Well, I think Planet Earth's age is 6000+.
  8. Mar 17, 2008 #7
    I agree that it is definitely 6000+.

    Okay, so this is a science forum, not a religious one. By agreeing with you that the earth is 6000+ years old, I coyly meant in the neighbourhood of about 4.54 billion years.

    I know that this is science forum, but i dont want to set aside my religious belief.

    Evidence that the Earth is much older than 6000 years comes from multiple branches of science: anthropology, astronomy, biology, chemistry, physics, and of course geology. All but anthropology (humans are relatively young) provide multiple pieces of extremely strong evidence regarding the incredible age of the Earth. The Earth is over 4.5 billion years old, and the universe itself is a bit more than three times as old as the Earth. This is a science forum. You can talk about your religious beliefs elsewhere, but not in this forum.

    To be on the safe side, and to offend nobody's religious beliefs, let's agree that the earth is older than 5 seconds. That should be an acceptable ecumenic consensus :rofl:

    :uhh:..5 seconds..?

    I read the bible, I don't think that the Earth is no more older than 6000 years.
    God created everything in seven days but a morning and an evening may represent geological period such as the Devonian.
    Genesis 1:20 God said Let the waters bring forth abundantly the moving creature that hath life ... We know that life started in the oceans, Cambrian explosion ?

    Adam was the first of all men or the first of a civilisation ?
    The story of Adam, Cain and Abel show the neolithic transition from the hunter-gatherer societies into agricultural communities that happened 9000 years ago and later in some place of the world.

    It sounds like you're really asking: do members of this forum believe what the Bible says, literally, or do they believe what scientific evidence says.

    As for me I believe the scientific evidence. Nothing personal against the more religious of those among us.

    The earth (along with the rest of the universe ) was formed last thursday with all the radioactive decay products and mineral deposits in place.
