Young earth creationism is valid and the macroevolutionary hypothesis is not valid

OK. You have none. You know nothing of the subjects of these threads, and you are totally incapable of writing a coherent paragraph or a logical exposition of your beleifs.

Unsupported assertion. No Big Bang theorists mention explosions, gigantic or not. The Big Bang was not an explosion. As with the Casimir effect, you are criticising without understanding. Until you have some basic understanding of cosmological theories your "criticisms" will remain meaningless.

Rhetoric is not evidence.

Yes, but youoffered rhetoric. Sort of. Your logic is only as good as your assumptions, and several people have pointed out how poor your assumptions are. Yup. I haven't made any claims, I have nothing to support. You're the one who has made a claim and supported it with no mare than rhetoric.

And the Casimir Effect is probably just the easiest manifestation of something coming from nothing to explain ... every particle in the Universe is surrounded by a cloud of virtual particles coming from and returning to nothing, and if they weren't our measurements would be very different from what we see. The Casimir effect: a force from nothing is a reasonably non-technical article on the Casimir effect, including the fact that it has a significant effect on
microelectromechanical systems (MEMS) such as the accelerometer that is part of the control system of the airbag in your car.

Not among those who understand the theory, are familiar with the observations, and do not have an axe to grind.All that your quotes from creationist websites evince is that they know the jargon a little better than you but, like you, they don't have any idea whereof they speak.
