As a Buddhist; I'm believing in re-incarnation. next life will defined by the "Karma" we collected (Good & Bad) in this life. as someone said, Like gravity, karma is so basic we often don't even notice it.
Kindly check http://www.buddhanet.net/e-learning/karma.htm for more details on Karma.
to give a straight answer to your question, Yes, there is a life after death. but it's not the same one we live now. where you will born, how your next life will be purely based on the karma we collected during our lives.
May peace be with you.
