Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists.

Agnosticism is the view or belief that the existence of God, the divine, or the supernatural is either unknowable in principle or unknown in fact. It can also mean an apathy towards such religious belief and refer to personal limitations rather than a worldview. Another definition is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist."

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.
