All I know I started it by myself studying theoretical physics, philosophy, ancient civilizations, mythology, religions, applied physics, universal history, etc. Any mortal has the ability to research and uncover our origins. And one of the criticism of an "expert" is the "qualifications" to discuss and argue.
The problem with self-education is that there's often no discipline. You find an intereting idea and you look for more information about that idea. On the other hand, if you get a proper formal education with "qualifications", they force you to read things you don't want to read, like the criticism of your favorite ideas. That's why people with "qualifiations" are less likely to fall for nonsense like pyramidology than people who have "educated themselves" by memorizing the Internet.
I suspect that you're reluctant to give us a reading list because your bias would beome painfully obvious.
Reason, logic and common sense is not available as a degree anywhere in the world.
Well, reason and logic are certainly part of many degrees.
As for common sense, dirt is common but it isn't necessarily valuable.
The Lord had a 'maximus' behind and in front... as Moses saw it.
According to Exodus 33, what Moses saw was God's "glory". Think of a very bright light. You can't look at it directly without damaging your eyesight but if it's pointed away from you - i.e. you're behind it - you can see it reflected from other objects.
