The best way to accept and rearch ones past you must first have faith in something. If you believe in Science then Evolution can be helpful. I believe that if you calculate a formula for the probelity of being here it would be 1/infinity.

What is the probility of your parents meeting and getting together and having you. Than go back to the problity of grandparents meeting and have your parents and them meeting. You can go back to when time began for your past and Scientificly we shouln't even be here.

If you are Christian you have Faith and Trust in a gracious loving God who sees all of us as his children than you can read the New Testament and find peace and affection for your fellow man by trying to be Christ like.

We all are revelent and find true joy and happiness in knowing others have our same experiences and helping them work through their struggle so we can all enjoy our time here on Earth.

I asked my mother and father about my own past history !
