It is impossible for an atheist to believe in life after death or rebirth because these ideas are opposed to humanist dogma and all atheists are humanists since what else could they be?. Since there is so much evidence of life after death, the burden of proof has shifted to the skeptics, they fail to offer a serious scientific explanation to justify humanism.
The sole purpose contradiction or argument these religious morons hold against atheism IS just philosophical at best. True that philosophy has it's place in our world but when philosophy turns into religious preaching it is then when humanity begins to lose the battle against these idiots.
I do not preach any religion, rather I ask atheists to use reason in evaluating the mountains of evidence for the survival hypothesis. It is too bad that all atheists/humanists oppose this scientific explanation as though their very lives depended upon it.
