Atheism is a belief system. It is the belief that there is no deity.
The scientific approach is agnosticism. In the absence of evidence, or what one considers evidence, the scientific answer is “i don’t know”.
Personal experience and evidence are two different things.
And a lot of what we consider to be scientifically proven, are theories, which are subject to constant change. The best example probably being atomic models and how rapidly they developed in the early 20th century. However that Bohrs atom model of circular movement of electrons around the atoms core was succeeded by more detailed models and the circles being disproved, doesn’t mean Bohr was any less of a scientist or evidence based researcher.
Meanwhile except for very few physics experts we all just accept that orbitals are the best approximation we have right now, because we read it in some book.

Aside from that, whether you accept and believe scientific discoveries remains a subjective choice. In social sciences like history or economics it often happens that two contradictory views are equally legitimate. And again the look in the past is valuable. Many scientists were ridiculed, sometimes even persecuted for their ideas to be outside the consensus of their time.
Assuming that what you consider the accepted truth because it is the accepted opinion of our day and age could proof equally fallible like the ancient Greeks and Romans ridiculing the now accepted germ theory, for which we have ample evidence thanks to the development of microscopes.

So your original ridicule is perfectly viable. It just not only applies to the statements of Tucker Carlson, who i probably despise equally as you do.
