Very informative as always..
...but seriously, you don't believe yourself that there might be a ''sorta spaceship''
under the Sphinx, do ya?
Well, most of your previous lessons, like the 11th, have some proof.
But these about human history sound a bit ''catched from the air'' (well i'm german but i hope you know what i mean).
Well, this is a review, so, your animations and sound a very good, everything fits to the topic.
At the beginning you said something like (i don't remember everyword): It's your thing if you believe it or not. i appreciate that.
Keep on this good stuff, but i hope you'll get back to topics like the Chakras.
One last thing: i dunno if you said it already somewhere, but, where do you get at this stuff? Studying something like Science, History, Spirituality at once?
Anyway 10 stars, because those are ''lesson'' (informatic) animations, and they ARE informative, however they are believable or not.
