This is the best Attack on titan book i'v ever read It was better than the show.

this book was the best, on a scale of 1-100 I'd give it a 100!! I can't wait till I read the next book. I've seen the whole series.

I agree with you levi. And did you take that name from Attack on Titan.

I think that was very educational and it really explained a lot about the earth's outer layer and earth's inner layer. I also didn't know that earth has so many atmospheres. And congrats to the Kurzgesagt group for finding all this information on earth. It takes a lot of time and money to do this.
