It has nothing to do with them being theist. (people can hate homosexuality if they're atheist too)
Yes, and the Large Hadron Collider could create a black hole that swallows Earth, but these two scenarios are extreme improbabilities. I understand you don't see the distinction between possibility and probability, but scientists tend to discount extreme improbabilities when forming analysis or offering guidance. Science regards all matters with doubt by default, and even much of Old science has been debunked by New Science. it is only the Strongly Evidenced ideas that break out of Doubt's gravity well and reach Living Theory outer space.This is why science is cumulatively providing a more and more accurate description of the universe, and why technology has been evolving so rapidly since the dawn of modern Reason. Meanwhile religion keeps offering the same shitty old Bronze Age assumptions for 2,000 years straight.
"Let's see. People were sooooo different back 2,000 years ago. They had 5 arms and 10 legs and 3 torsos and eyes and ears in abundance back then. But we have evolved into something more practical over the last 2,000 years, right?"
People are basically the same, now, as they were back 2,000 years ago. That's why religion fits us now as it did back then. That's also why he con artists of whatever religion are still trying to pull the wool over the eyes of the common people. The difference is that this time it is the religion of modern science.
In all those spactacular theories of modern science that suggest all kinds of grandios happenings in the universe and among people, from evolution to the Big Bang and beyond, all are just theories. There is so extremely little fact among them that they are basically science fiction. And because they are believed as truth among many, science has become religion more than it is science by far... at least among the common people.
The new high priests are the scientists who lie through their teeth about the truth of the theories. There is no truth to the theories. The only truth is what is factual.
