There is no greater threat to science than atheist mentality.
Highly religious Theists invented the scientific method, classical physics, electromagnetic theory, and quantum theory. After atheists finally took over science in the late 1960s and early 1970s and claimed religion was holding back science, we immediately stopped finding cures, physics became stuck with untestable theories, and technology started growing much slower than anticipated.
Atheist mentality is that everything outside of the evidence, outside of the box, outside of your personal incredulity, outside of what most scientists believe is fantasy and imagination, nonsense, fictional, foolishness, magical thinking.
Atheists try to prevent people from thinking outside in this way or having creativity and imagination because thinking outside is viewed as nonsensical fantasy to most atheists. That's why they discourage thinking outside of the evidence.
In the past when Theists ran science, creativity was not discouraged like how it is now intentionally by atheists.
When we look back at the history of science we see that vast majority of the ideas that caused science to grow the most were all ideas that were initially viewed as nonsense, and these ideas were outside of what most scientists believed.
Since atheists run the peer reviewed journals now, they only let in ideas that match into their own personal incredulity otherwise it is viewed as nonsense and fantasy and not let into peer-reviewed journals.
If atheists hadn't taken over the peer reviewed journals, and creativity and imagination wasn't intentionally discouraged by atheists, how far do you think science would be?
Since atheist mentality causes the greatest destruction to creativity and imagination, how far do you think science would be if Theists still ran science?
