Too right they’d be warmer. But do you know just how much warmer?
Let me tell you.
Twenty. Two. Thousand. Four. Hundred. Degrees Centigrade.
Four times hotter than the surface of the sun. Four times hotter than the highest known boiling point of any chemical element.
And that’s just from accelerated nuclear decay alone. Catastrophic plate tectonics, and all the other accelerated processes on top of it, would bump the temperature up even higher.
And no, this wasn’t some kind of “secularist rescuing device.” It wasn’t some sort of attack to “discredit creationism.” It was the young earthists’ own admission.
Don’t believe me? Here’s a link to the place in the RATE project technical report where they do the calculations:

And here’s a link to the summary, where they admit that they don’t have any explanation of how the heat could have been removed:

Seriously, with admissions like that, is it any wonder that the world considers young earthism a joke and scientifically educated Christians consider it an embarrassment?
