Jesus is the one who came to Earth to save us all. He rose from the dead about 3 days later and came back to life. Jesus was God's son (God felt that Jesus was the one he felt to pick so he is not his real son Mary and Joseph were his real parents.) Mary found this out when an angle told her that her son would be the messiah. (Jesus). Jesus gave his life for our sins so it was not something we had to remember. Jesus will come back one day but it will be a long time. Jesus was not forced to die for us but he choose to because he wanted to be happy for us so he suffered for all of us even the bad. Jesus was very popular and important because he could cure anyone. For example he cured a paralyzed man while he was sitting there saying he would never be able to walk and after one prayer he was able to walk. Jesus works miracles! :)
The answer for this is because of the recourses. There is a lot of food (seafood) and materials to be able to live life in and flourish in. Its actually pretty cool.
