Okay let's tone it back a bit.

The medievil age, or dark age

Historians don't call it that. The "dark ages" were called that because we didn't have good records of the period, i.e. it was obscured to us or "dark" to us. That's not the same as the ages being regressed or evil in any fashion. Also, "medieval" doesn't have anything to do with "evil" (I don't know whether you're implying that or it's just a typo, TBF), it literally just means "middle ages" - "medi" >> middle, "ev" >> ages (or period), "-al" >> "of the" (just the normal suffix used in english).

Because of the insane misconceptions, medieval historians tend to avoid using the terms "dark age" or for that matter "feudalism" (feudalism is a vague term that usually implies vassalism, serfdom, and manorialism, and lots of places didn't even have all 3 during the "feudal ages" let alone during all the periods described of as "feudal").

When humans used to burn women because of superstition and persecuted scientists as heretics.

This is overblown. The classic example of 'persecuted scientists' is Galileo, who was mostly 'persecuted' because he talked mad shit about the pope, made explicit statements that weren't even backed up by his evidence (you could say "well this evidence seems to suggest heliocentrism pretty strongly" and the church wouldn't do shit, but IIRC Galileo explicitly said "the world is heliocentric and the evidence proved it", except his evidence didn't actually prove it (Foucault's Pendulum did, but that was ~1850 not ~1660).

Similarly, when witch burnings did happen, it tended to be in the more ignorant obscure villages, not cities. The Church hated it, because... witches aren't real. You can't make a deal with the devil to gain magic powers, that's heretical nonsense. Witch burnings were the antivax movement of the day.

When disease killed a quarter or so of a population. When people died due to a bad tooth or a broken limb.

When education was based a century’s old fiction book.

It took many curious and courageous lifes to establish the scientific method.

No, the basics of science existed during the medieval period, and in fact scientific development and refining of the core concepts of science during the medieval period was a necessary part of eventually establishing the scientific method!

The other necessary part was improving the precision of tools (that includes things like improving our glass for test tubes) so as to make scientific experiments physically repeatable in the first place. Same problem as for automated production via machine tools, in fact.

This scientific method enabled us to go from riding horses to flying to the moon. To have pocket sized computers, that connect and enterntain us.

It wasn't sufficient but it was definitely necessary.

Although to be a bit needlessly contrarian, people were still riding horses for commercial reasons during the space race, for practical reasons - if you're a veggie seller selling veggies via essentially the "ice-cream truck business model" (i.e. rolling down the street and ringing a bell that indicates people can come out and buy vegetables from you now), you don't need a truck to do that (you're stopping and starting whenever someone comes and buys vegetables so you don't benefit a lot from 40MPH,60KM/h), and a horse-cart can carry quite a lot of vegetables without needing to constantly drink oil. Also, the horse is self-driving, and maybe will cheekily start walking before the vegetable-sale has completed, because the horse isn't stupid and knows it's about to be told to start walking anyway. And in the 1960s, a truck is still quite expensive so if you live in a rural town selling veggies, you might pay more on the mortgage/lost interest than you gain in productivity anyway.

Honestly a lot of cars/trucking is completely stupid and should have been replaced by an "electric horse" (i.e. a low-speed vehicle, think horse-walking-speed and definitely sub-20MPH,30KM/h, which could thus be electric without much loss of performance) with most long-distance transport done via rail. And forget Elon Musk, we could reap a lot of the benefits of self-driving cars by simply deploying trained corgi chauffeurs (i.e. a less fuel-intensive alternative to a horse, which has more than ~1 horsepower since it's driving an electric vehicle).
