no KNOQW about this
what is this,what did you actually mean dude.
old earth can know with calculation chemical theory
you really cannot calculate the age of the earth only thing you can do at the most is speculate the age,assumptions are not facts and so it is not believable
I have to disagree. You can calculate the age, and then you have an error bound.
For example, on this forum we could even agree, the age of the earth is somewhere between 5 thousand and 5 billion years. But scientifically, we can get much more precise.
There is no way to get exact. When did the Earth form? Was it when 90% of the material on the Earth today had formed on the then primeval Earth, or 95%, or 99%? You pick when it "formed."
