An what about that other planets? Are they flat too?
I don't believe so, and I actually question the logic of referring to these celestial bodies as "other planets." We've always done it in the past because it's what we're used to, but using that term suggests the RE assumption that these bodies are similar enough to the earth to expect similar basic characteristics. That, of course, leads to the old question, "So why is the earth the only planet that's flat? Why is it so special?"
This is why I find it difficult to believe someone could believe in a flat earth without associating it with religion. It seems odd that this would be the only flat plane in existence without some higher power determining it is so. I'm curious to hear athiest FEers remarks on this, do you think that the flatness of earth, the uniqueness of it, contributed to life forming on our planet? Although since I suppose you believe we have not observed any other planets or moons, you believe there very well could be life on them.
