For any one of us to find the answer to that questions, first and foremost we will have to go through a passage, to which i am afraid their is no return (yes you guessed it DEATH.) That passage is like a door to the next (whatever yall wanna call it) existant. just like there is PAST-PRESTENT-FUTURE. the PASSAGE (passage 1) that existed between the PAST and the PRESENT was being BORN and this leads us to our PRESENT. The PASSAGE (passage 2) between our PRESENT and the FUTURE is DEATH.
In reality no one has any recalls or memories of anything prior to their birth, just like no one has or will ever come back from the death, and has talked about what happens when you go through the PASSAGE 2. The point that i am trying to make is that the only possible way of us getting the answer to that question at this point in time i.e. PRESENT, is to go throught passage 2 and the only obsticle to this passage is a "little" thing called TIME.
