Yes. The Middle East exists as a place where people live and raise their families. It just happens that many Middle Easterners do not have warm feelings for their neighbors.
Riyadh is not known as the Middle East. Riyadh is an important city in the Middle East and the capital of Saudi Arabia, but the Middle East has a lot more than just Riyadh.
There is no difference in nomenclature. Muslims in the Middle East pray in Masjids and Jame'as (Mosques) just like all other Muslims.
Muslims currently live all around the world, not just in the middle east
the middle east is another country's they just speak different language's and have a different cultural but some of the middle east con tries are very cool and very nice.
Not really, just in the middle East and 'Murrika'
They drink bottled water. Yes. It rains in the Middle East, just not terribly frequently. Just because places are scrubland or desert does not mean that they never receive rain; it means that they receive rain less often than most other places.
Turkey is (Azerbaijan and Georgia are as well but they are just north of the area known as the Middle East, and are not considered a part of the Middle East themselves).
Which countries are included in the "Middle East" is often open to interpretation. It is more a general than a specific region. It is just a general term used for that part of the world, and what "that part of the world" is depends on who you are talking to and the context. For that reason it is difficult to specifically answer your question.
Middle East
The Middle East is a subregion of Asia. I assume by Asian you mean East Asia. India is not a part of the Middle East or East Asia. It's in its own subregion: South Asia. It can be also referred to as the Indian subcontinent but can be offensive to Pakistanis, Bangladeshis, Nepalese, Sri Lankans, and Bhutanese people because you would be using the name of a country (India) to refer to a region that is more than just India. For this reason you should use the term South Asia instead of Indian Subcontinent.
Religion is just one of the causes.
Most Middle Easterners live in houses or appartments, just like in the West.
