Fossils, according to the museum's creator, are the result of the great flood, for which Noah built his Ark. This was when he rounded up two of every species on the planet in order to preserve the gene pool (funny, I wonder how he determined the sex of the waterstriders, newts, tarantulas, and coelocanths that were on his Ark. Well, I guess he just was lucky...). I guess carbon dating may not be that accurate after all.
In one of the museum's displays, spooky Chucky-like animatronic human children can be seen playing while a Stegosaurus munches on foliage behind them. The museum claims that dinosaurs and Homo sapiens cohabited the planet.
It is believed that we are separated from dinosaurs by at least 60 million years. Again, bus-sized dinosaurs lived 60 million years ago, but the museum claims them to be ten thousand times younger than that.

If what the museum claims is true, the great Irish elk, thought to have lived around seven thousand years ago, would have died off around a thousand years before the world was created.
If God had created it in the first place, why would he have allowed its extinction?
