Just jumping in here. I would definitely say 6000 years old, give or take.
If we're being lied to about the earth being round (with me the jury is still out on that), doesn't it make sense we're being lied to about where everything came from? I'm already a geocentrist; I believe in the big bang--God spoke and BANG! it happened! I'm just unsure as to whether the sun goes around a sphere or, for lack of a better term, a disc.
I know the question was directed to another poster--but dinosaurs existed along with man. They're referred to in the book of Job--but they're not called dinosaurs, but rather behemoths.
The amount of deception in this world is just crazy. You could spend a lifetime cutting through all the garbage to get to the truth.
