> am certain that some of the ideas that many of us hold now will be thought quite silly in a few hundred years. Yes, like the theory that we're actually living in a simulation, espoused by Elon Musk and other respected, ostensibly science-minded people. It's basically Creationism in modern form.
It isn't like creationism because it is based on some otherwise currently unexplained observations such as quantum mechanical behavior and magic physical constants. The idea is that these are exactly the sort of observations you'd see if you were in a simulated universe. Now if we were to observe new species being created in N days, for small integer N, then I suppose your assertion about creationism would also hold.
Also, creationism isn't limited to only 6 day creation, that's more of a modern thing by people that insist on taking Genesis 1 (which is poetry) literally. Early Christian thinkers postulated that 1 Genesis-day was actually 1000 years. Creationism just says that God created the world; how long it took and how he did it are implementation details.
