There are few conclusions in science, you should know that, there's merely a next theoretic stage. We don't know the origins of the AIDS virus or SARS-CoV-2. It took 30 years to prove cigarettes definitively caused cancer after the first Doll & Hill 1956 study, but we could see the connections. Same here, we can see the connections beginning in 2017, and now we have over 200 studies that suggest and prove in parts and piecemeal like the Doll & Hill study that phones are bad for kids.

Gesturing broadly at a lack of conclusive evidence is simply naysaying the connections that educators, child development experts, neuroscience researchers are detailing. If you can't counter their connections and simply sit on the ledge of denial, you ain't thinking, you're in denial.

Stay in storytelling.
