Afraid you'll be some 200 years off of Usher's calculations as well?
As Mr Hovind pointed out:
If we don't know where God came from, and you don't know where that primordial atom came from, then don't call what you believe "science," and what we believe "religion."
Not over math though.
No, you don't have to accept them.
It's your freewill not to have to.
Others have done it for you, and I posted Usher's chronology for you, and now you're retreating behind your craft (science) and telling me this is a science forum, not a religious forum.
I figured you'd pull something out of your hat, if I was to do all that work and show you my calculations; and I rejoiced when I saw Usher's calculations in chart form.
So I posted it to see what you'd say.
And sure enough, I was right.
In short, if you won't accept Usher's calculations, you surely won't accept mine.
And I never did expect you to do the math yourself, either.
My point stands.
Earth may be extremely old, but it has only been in existence since 4004 BC.
