If you take, let's say, 10 thousand years, and try to explain every single detail of our planet, in all branches of science involved, you get the whole picture completely painted, without contradictions.

Big numbers are just imagination, there's nothing you can prove about it. The so-called "measured" numbers of the age of different fossils etc. found are actually selected numbers of years: they pick the ones they agree with their theory, and discard all the others (that is, the majority). Very scientific, indeed :/
