A thousand years in the bible is, a thousand years...
Biblical history tells us that Adam was created approx. 6000 years ago...A thousand year day lines up exactly with history and prophecy...
I was going to address your post, but then I read your tagline and decided not to.
Do The math
One day is a 1,000 years in God time.
Adam lived 800 years.
800 x 365= 292,000 days times 1,000 is 292,000,000 days. Divided by 365 is 800,000
So Adam lived 800,000 years in God time.
