I strongly believe in God and afterlife, but it is impossible for science to prove existance of God, however a lot of neurosciensts who study brain are sure that afterlife exists, also maybe i am completly wrong but there are 2 options: 1) Universe created itself; 2) God created universe... in first case, the law of conservation of energy doesn't work, because universe can't create itself from nothing... second case implies there is another spiritual world, with another laws, so the law of conservation of energy is allowed not to work there
