It doesnt matter what you think or what your beliefs are, the truth doesnt change. Of course we reincarnate. Its the only logical explanation. We have all incarnated on this earth many many times. If we just lived once we wouldnt have to learn anything. Earth is sort of a place where we put into practice what we have learned from the previous incarnations. One life heaven or hell, its just rediculous.

It is neccissary to return to earth until you have learned all that you need. Even if you dont want to return, you must in order to complete the solar cycle. Once you have done this you can then move on to other systems, but still able to come back to teach others.
