I have been thinking on this. I don't believe the earth is flat as Eric Dubay says.
I recently have taken a class in college about astronomy. It is well proven without a doubt that earth is round.
You can prove it to yourself. Just look at the moon. Is it round? It it looks round to you, it doesn't matter what other people think, do you think that it is a round flat disk orbiting our planet? How does it goes into different phases? Now, think about this, is earth a flat disk floating into space? When the moon goes into different phases, except on full moon, what covers the moon? A flat earth disk?
I have been to Griffith Observatory many times, I live near there. I have seen different planets with telescopes that they have. None of the planets seems to be a flat planet orbiting the sun to me. Why would earth be different from those other planets?
Now, it's okay to me if those books make you think different. I'm not gonna shun you for that. The Watchtower society manages people to think different from the rest of Christianity using the Holy Book (even going beyond what it is crystal clear in there). Could it be the case that Mr. Dubay is trying also to cause controversy on well establish scientific evidence?
Just my two cents.
