how many lifes do we really have?
That is a very good question. Although I do not believe in reincarnation, I do believe, if you are taken out of this world before you can show who you are. Through God's will, you can return to show who you are on earth, the same as all of us. Reincarnation is not a luxury for us to use as a whim to existence. It is on the other hand a way to save your soul.
