Current theories on the creation of the unviverse state that, if it were created at all, as it were, unoficially, it came into being between ten and twenty thousand million years ago. By the same token the earth itself is generally supposed to be about four and a half thousand million years old.

These dates are incorrect.

Medieval Jewish scholars put the date of the Creation at 3760 BC. Greek Orthodox theologions put Creation as far back as 5508 BC.

These suggestions are also incorrect.

Archbishop James Usher (1508 - 1656) published in Annales Veteris et Novi Testamenti in 1654, which suggested that the Heaven and Earth were created in 4004 BC. One of his aides took the calculation further, and was able to announce triumphantly that the Earth was created on Sunday the 21st of October, 4004 BC, at exactly 9.00 am., because God liked to get work done early in the morning while he was feeling fresh.

This too was incorrect. By almost quarter of an hour.

The whole business of with the fossilized dinosaur skeletons was a joke that paleontologists haven't seen yet.

This proves two things:

Firstly, that God moves in extremely mysterious, not to say circuitous ways. It is not an experiment. God does not play dice with the universe; He plays an ineffable game of His own devising, which might be compared, from the perspective of any of the other players (1), to being involved in an obscure and complex version of poker in a pitch-dark roomm with blank cards, for infinite stakes, with a Dealer who won't tell you the rules, and who smiles all the time.
