And who did Jesus die for? What is Heaven for ...and who goes there?

What would be the supposed cut off point ...would it include the ape-like creature going to Heaven, or would it only include all creatures that came after the supposed (not yet found) missing link? And when did accountability come into play ...if we believe in Heaven, do we believe also in Hell? And what about the criteria? I would feel real bad, to deceive someone concerning a thing of utmost importance!
