I agree. I have always been really curious about cosmology. Used to think about it all the time when I was a little girl, and watched all of the available documentaries. Then I became an archaeologist. And even as an archaeologist I managed to keep on exploring my interest in cosmology, researching on ancient civilizations cosmogonist systems, the explanations the old and wise would have for what happens on earth by looking an interpreting what goes on in the sky. 5000 years ago, the very first ancient Egyptians, for instance, knew a lot more than any European person knew in Europe during the middle ages.
But you're right, if people were all given the chance to follow the latest researches at school, if it were to be public domain maybe we would all be a bit more open minded, and we would be confronted with less religious fundamentalists. I'm sure the lords of war wouldn't be able to use religion as an escape goat for their own personal interests as much as they do!
There is nothing like an educated world, if the mission is to fight things such as ignorance and injustice!!!
