"The Big Bang theory cannot seriously be questioned, due to the enormous volume of evidence".Clear, as that's what I replied to.
Nope. It doesn't. It came from the preceding state, which was well known.
Self-referential is the assumption that the current condition of the universe provides evidence of the theory based on observation of the current condition of the universe
It doesn't do that. Learn some science in general, and educate yourself -- preferably somewhere other than The Creation Institute or some other humbug -- about cosmology in particular.
The current condition of the universe is based on past conditions. We can run that clock backward to within literally a few microseconds after the singularity. In particular, as just one example, the relative abundances of light elements in the universe is entirely dictated by very elementary thermodynamic principles. They are not consistent with any literal creation myth, which all make entirely different predictions if one tries to press them into science. (They are legends, so this can't be done.)
"The Big Bang theory cannot seriously be questioned, due to the enormous volume of evidence".
There is roughly as much evidence of what happened in the universe after the first several microseconds as there is that the world is round. That's not my "religion" or anyone else's.
It is not my intention to disprove your religious beliefs.
You would not be able to do that, even in principle, since religious beliefs are outside of that kind of argumentation. What you will not do, is argue that a scientific fact is not a fact because a bogus interpretation of the Bible says it isn't.
The sad thing is that Young Earth Creationism is a relatively new phenomenon, largely created as a reactionary opposition to science. Before the Reformation, there was literally no one who believed that the creation account of Genesis was anything other than a metaphor. Even in the earliest years of Protestant literalism, no serious theologian had waded into those waters. It's strange how the scientific thinking of some (but not all) parts of Reformed Christianity have gone backwards to far more primitive thinking. The original church did not set an age for the Earth; wisely. The Catholics never have.
