    I cannot speak to the quality of the documentaries you’re watching since you don’t actually list them.

    But I can assure you we are extremely confident we know the age of the Earth. In fact we have known the age of the Earth with high confidence longer than we’ve known age of the universe that contains it.

    The ages of various life forms on the earth are much more nebulous but the age of the actual rock that makes the planet up, is known.

      We know the age of the universe? Please, that’s ridiculous. We don’t know, we have done math, and made guesses. If we have an age for it, it’s just a theory.

          Are there any assumptions made, in the determination of the age of the universe? I’m pretty sure there are. If so, then it has not yet been proven and its a theory.

            Oh well if you’re “pretty sure” then I won’t argue with you.

            After all, you have a feeling on the subject. Don’t bother to look it up or anything. Remaining deliberately uninformed is so much more appealing doing a quick Google search.

              I don’t need to do a search. We have not proven the age of the universe. What some scientist says it is, may be based on research and math and whatever else, but its still a theory.

              Kind of like when they look at a star in space and then tell us what that star is made of. They do not know, they are guessing, based on other things we do know. But its still only a guess. What it is made of can’t be proven without going to that star and testing it, which has not been done.
