Actually, by this logic, it's pointless to be religious. There are so many different religions and beliefs, if you assume all have the same chance of being valid, your chances of following the right religion are so close to zero it would be like winning the lottery. That's only if one of the religions out there is even right to begin with.
We have no evidence that there is anything like a soul or something that moves on after death. Thus, it is almost certain that when you die, you're dead.
