We didn’t just start using our brains like that in recent time only. There may have been a few Albert Einsteins in the stone age but if they couldn’t spread their ideas, then that civilization did not have that knowledge. Leather tanning and meat conservation can be discovered easily, but it has to be rediscovered every time there’s a new group of 20 people, it doesn’t get transfered to be improved upon over the centuries.
The problem your reasoning is missing is scale. We know you can’t build the Great Pyramid if your busiest cultural center is a village of 200 people in the closest 100 km and they couldn’t communicate.
And all our tech is based on improving upon something that exists. No one can conjure a microchip and a cell phone out of thin air.
