Salam. If the person lives in another country and has the wish to be buried in Iraq, there are governmental regulations about shipping a person's remains. The country where that person lives has laws that need to be followed. For example, the person who died would need a medical statement that the body is not contagious. The casket would need to be inside a lead box that would not leak, then placed inside a wooden crate which is nailed shut and has special seals that show if there was tampering or opening. The funeral home would need government permission to transport the body by airline and not all airlines provide that service. The licensed funeral home worker would need to drive the prepared package with the person's remains to the licensed airline and make sure that the remains were placed on the airplane.
At the arrival in the airport in Iraq, the person's remains would be in the customs area and the customs workers would wait for the person who would need to personally claim the body and sign documents that the body was picked up. Because the whole thing is very heavy and would not fit inside an ambulance or hearse, the wooden crate would need to be opened which means workers or relatives of the deceased would need to use crowbars to remove it. After lifting the lead box into the vehicle, the deceased would need to be transported to the cemetery location where the bodies are washed. The cemetery would take care of everything but of course the price will depend on the location of the cemetery.
The most expensive part of the international burial is the western country (funeral home, trip to airport, airline shipping) and could reach $15,000. The price of the cemetery plot, washing the body, wrapping the body in kaffan, is a separate price. The temporary grave marker with the name written in chalk on it is probably free, but the grave stone with the name carved on it would be a separate price.
This does not answer your question of whether someone can be buried in Iraq, but I just want you to know that the person needs to save his money if he has such a wish. May Allah SWT grant all halal wishes.
I suppose it all depends on the person. But yes, if someone took a literalist approach and did believe that the many strories of scripture were all true in a black and white way, and they simultaneously were consistent in believing all things they viewed as miracles, then yes they would believe both in the literal story of Adam and Eve, and the literal story of the virgin birth.
