That simple statement doesn't need to be "quoted" from anyone. It's a statement based on one's understanding of science. It conforms with my understanding of science, which I have studied for over half a century.
"Facts" are simply direct observations. Often we accept facts that have been observed by others who are reputable, who have no particular agenda, who have no reason to "spin" what they have observed.
It is not easy to describe what a scientific theory is. So I tried ChatGPT, and I think I got a good description:
A scientific theory is a well-substantiated explanation of a natural phenomenon that is supported by empirical evidence and has undergone rigorous testing and verification through the scientific method. It is a logical and coherent framework that seeks to explain and predict the behavior of a particular aspect of the natural world, based on a set of principles, laws, and empirical observations. A scientific theory is subject to refinement and modification as new evidence and information are discovered, but it remains a reliable and robust framework that explains the available evidence and makes testable predictions about future observations.
When I first got online, back around 1998 (?), the discussion forums I was interested in were science forums. I was, and am, a proponent of mainstream science, as opposed to pseudo-science.
But with the advent of the awfulness of Trump, I've found that it is difficult not to call out his lies and argue against those who have believed his lies, especially his Big Lie. It's more than just keeping one's writing skills sharp -- I think Trump is a serious danger to this country in his pandering to white supremacists, anti-semites, misogynists, replacement-theorists, Qanon wackos, and the rest of his deplorables. Trump has loosed and emboldened right-wing domestic terrorists; he thinks he is above the law since he has yet to be charged with anything. This must change. He must be held to account, especially for his attempt to, yes, steal the 2020 election -- his biggest and most obvious projection.
So, maybe my comments here don't change anyone's mind. But if no one opposes Trump's lies, I expect more people could tend to believe them. As respected conservative Judge Luttig testified, under oath, Trump and his allies are a 'clear and present danger’ to American democracy.
