Is planet Earth actually 'Hell' in disguise?
"Hell" is something in religion, most notably in christianity nowadays. So, if Hell exists, it's likely adhering to some description in the christian scriptures. And it says in the Bible that God created Earth, and that God loves us. So He didn't create Earth as a Hell.
Other religions have something similar to Hell, and the only ones I can think of where your picture of Earth may apply is the ones that state that life is misery and pain and should end as soon as possible. Not very many exist.
Yes, but fortunately it occupies only a very small portion of the planet, and it keeps moving location! Currently it is located at 1600 Pennsylvania Avenue NW in Washington, D.C. USA, but strangely it moves to 1100 S Ocean Blvd, Palm Beach, FL 33480, USA most weekends.
