I recall a pretty neat elaboration on seeing the world with a sense of wonder. It was by Richard Feynman, Nobel laureate and notorious and vocal atheist.
The idea that science is one special aspect of the world and can, therefore,
not have all the answer, is flawed.
Science is knowledge of the world. That's all it is, knowing about the world. Not believing, not guessing, not conjecturing, not assuming or demanding. But observing the world, figuring out how and why it works based on what can be observed.
I won't bore you with repeating what I wrote about this only eight years ago:

Cold, hard science, if anything, helps to marvel at the world. I know it let's
me see the magic, where I define magic as magnificent and amazing stuff that just impresses me in all the ways I cannot comprehend.
Science is why I can marvel at the ongoing repetition of the number Pi appearing in nature. Yes, it's all just because of circle, I know. I know because of
science.
Science lets me marvel at how everything I touch is made from the same three things, just in different arrangement. Protons, neutrons and electrons. At how, actually, I can only ever bring the negative electric fields around the nuclei of my own atoms into so much proximity with other such negative electric fields, but no real matter ever really touches other matter.
With these same electrons, it shows me that, fundamentally, the universe is undecided and quite loopy, when the electrons are blasted through the double slit.
Science tells me where, in my head, exactly, and in yours, and in that strange fella from Turkmenistan's head, we make moral judgements about people we see*, and that the little, involuntary expression I make when I'm happy to see someone is the same expression the little girl from Sudan or the grandfather from Peru make**.
Science shows me stars, and planets around stars other than the sun. It shows me the very bang of the big bang, the noise itself, from the cosmic microwave background, and it shows me how a bee will transfer genetic material from one flower to another. How and why exactly a child is so easily befuddled when you hold your hand in front of their eyes***. That an infant will recognize a human face, but cannot distinguish skin-color or other features of ethnicity ****.
The majesty and grandeur of it all is too big for me to describe, as verbose as even I am. I don't know any poet can. Scientism is just another word for preferring certainty and sure knowledge over any
substitute, while also humbly admitting the limitations to that certainty or surety. Considering what messed up stuff there is to know, I cannot find much fault there. It may not
always be pleasant to
know. But it's honest.

** there are certain microexpressions that are universal, even the blind who have never seen anyone make such an expression display them, according to the work of Dr. Matsumoto. I think I recall happiness about encountering someone is one of them.
*** Object permanence, the ability to conceive that an object exists even when it is not perceived through the senses, is a feature the brain doesn't fully wire up for until about age two, younger kids only get to enjoy bits of it. See Dr. Piaget's theory of cognitive development.
