Why am I this brain and not another brain, I heard that if a sample of DNA was taken of me and I could be brought back to life in 1000 years it would be a copy of me but I wouldn't actually be me so to speak, Is this correct? Why am I not in control of someone elses body. To quote Richard Dawkins: "We are all extremely lucky to be here, the amount of other possible people that could of been here in my place outnumbers the sand grains of sahara. If you find about all the different combinations of ways my genes could of been polluted, we are all extremely lucky" Is this saying my current DNA is the only way I could of been me? What made me be this exact DNA? Why wasn't I born 10,000 years ago in my family history? Have we really all won a lottery of trillions to one odds to be here? Far greater odds than any lottery, ridiculous odds. These are the questions I have been thinking about recently and would like answered by people more educated than me in this field. Hope I can get some answers, thanks.
