That's weird. You're convinced of the strength of your memory when it comes to the map of the world, but you can't remember the title of even just one book that informed your learning? Certainly buttresses the suggestion that your memory is more fragile than you care to admit.
I'd argue you'd be more likely to remember the title of a book with content in which you're interested, than you'd be to recall the full details of the world map. So...
Ok genius. Sorry that I can't remember the names of books of I read over a decade ago. I would argue remembering interesting facts in books that connect with you on an emotional level are easier to remember than the name of a book. For example, I remember where I was and how I felt when I first heard of what happened on 9/11. I was in my 1st period class in middle school when the principal made an announcement on the intercom. I remember the content of the message and I remember how I felt at time. However if you asked me to remember the name of my principal I couldn't. If you asked me to remember the name of my first period teacher or first period class I couldn't. Hell I couldn't even remember how they looked. But I can remember what he said. I can remember the discussions I had with classmates afterwards.
I know what I remember learning about human migrations to Australia even if I don't remember the specific book titles. I remember it because of the awe it made me feel to know humans from 50,000 years ago were able to traverse hundreds of miles to open ocean to reach the Australian continent. I remember looking at maps and thinking wow how could humans have done this. I personally remember feeling totally frightened if I would have made a similar journey.
Just like you couldn't convince me I didn't hear about 9/11 for the first time over the intercom in my first period class at middle school simply because I couldn't tell you the name of the class or principal, similarly you can't convince me I didn't see Australia located where I remember seeing it located for most of my life and that is thousands of miles south of it's present location.
I've just watched it, and I'm concerned about your ability to process things. If you paid any attention to the context, it's apparent that when she says Australia is far, it's in reference to the journey from Africa/Middle East. Maybe you should watch it again, because I don't think you were paying attention. It might explain why you didn't know where Australia is located on the map of the world.
Swimming across the channel is no easy feat, and takes a lot of preparation. It'd be a particularly useless mode of transport for a migrating people.
Australia is a lot larger and has a harsher terrain than Papua New Guinea. I think you're reaching here. China is close to countries like Tajikistan and Uzbekistan, but in the discussion on human migration, China is the proxy for the populating of that region.
I don't think your memory is as great as you think it is. I'm also convinced you're not as perceptive as you think you are. I don't say that to be insulting, just that it's the case with all humans.
Once again I'll give you bad memory if I only looked at maps sparingly.
Dude this is shyt I loved researching and studying. Hell beyond Australia, Papua New Guinea always fascinated me primarily because of their African apprearance and my love for black history globally. You can check my history I've posted significantly on almost every topic involving black and African history. I think I would have noticed Papua New Guinea is right next to Australia in all my years of learning about it. Like that is something I would have made a connection with.
Instead seeing the world map now with Australia this close to Papua New Guinea is a mindfukk for my consciousness. I don't know any other way to say it. Its tripping me the fukk out.
