Why do Star Trek characters live so long?




In Star Trek (2009) Spock has come from the year 2387 to what is presumably about 2245. How can he and the rest of the Enterprise crew live to be so old? Are star dates not the same as our Earth years? Does traveling at warp cause you to live longer?




in all the other instalments of star trek i noticed that the characters were atheist are the star trek enterprise crew supposed to be also?
