That's what most of people believe in
But a large number of people are not educated in science:
- due to people focusing their career and education in other non-scientific areas, like business, trades, owning shops that sell products, farming, etc,
- due to poverty in population,
- and due to lack of infrastructures in the poor countries.
Let face it.
- How many children and young adults in Muslim-majority countries get the education required to get careers in science and technology?
- And of those groups that do, how many of them become qualified biologists?
In richer Muslim countries you may have higher percentages of people receiving higher education qualifications in science, but when you compare the rest of the world that are Muslims, well, the picture is not very bright.
I have no idea myself of the global Muslim demographics, but I am guessing that those who do become biologists, would only represent a fraction of 1% of the hundreds of millions of Muslims.
And it would be the same in other global demographics of non-Muslim societies. Not everyone chooses to do higher education in biology, and even less people get involve in astronomy and cosmology.
That being the case, then without the education and experiences, how many people who don't believe in evolution or the Big Bang or whatever scientific discoveries, then the numbers you are talking about are really meaningless.
