Perhaps they react this way because to believe in a personal Creator God requires not only recognition but respect and obedience to Him? That is a bridge too far for some. They enjoy having their own autonomy and no "higher power" to answer to.
Something like that is my guess.
It’s funny that Sir Fred Hoyle was left off of that list of ‘objectors’, since he’s the one who coined the term The Big Bang.
Hoyle hated and rejected the Big Bang expressly because he spotted the eerie similarity to the opening lines of Genesis.
But...
later in his life came this:
“As part of this work, Hoyle invoked the so-called Anthropic Principle to make the remarkable prediction, based on the prevalence on Earth of carbon-based lifeforms, that there must be an undiscovered resonance in the carbon-12 nucleus which facilitates its synthesis within stars. He calculated the energy of this undiscovered resonance to be 7.6 million electron-volts, and when Fowler’s research group eventually found this resonance, its measured energy was remarkably close to Hoyle’s prediction.
“It was also this work that caused Hoyle, an atheist until that time, to begin to believe in the guiding hand of a god (what would later be called “intelligent design” or “fine tuning”), when he considered the statistical improbability of the large amount of carbon in the universe, carbon which makes possible carbon-based lifeforms such as humans.
