All of these things were denied by "experts" at one ime or another.
Roundness of the earth
The earth floating in space
conservation of energy - Eccl, 3: 14
"Cords" of Pleiades and Orion (gravitationally bound star groups) Eccl 1: 9
Uncountable number of stars
You can count the visible stars, around 10,000. But you don't live long enough to count the trillions of stars that we now know are there.
Expansion of the universe
God stretches out the heavens - (present tense)
Those are tedious cherry picked ad hoc reinterpretations rather than any kind of demonstration of knowledge at the time of writing.
