Christianity says that there is an afterlife but proposes no evidence for this. Also the historic nature of the bible and the differences in interpretation also hinder its scientific validity. This is also the case with the Quran therefore these two religious texts bear no scientific evidence to show there exists an after life.
There are cases of near death experiences where people die and come back to life and they say they have seen dead relatives or family members. There are also cases where people die and see a white light. But why are these guarantees of an afterlife? These both could be a feature of the human brain and how its function. It does not mean that there is an after life. There are also sightings of ghosts or dead family members. Yet there is still no scientific evidence for sightings of ghosts.
So where does this leave us? Well lack of evidence does not necessarily mean that the after life does not exist. But as a true believer of science I do not see how an afterlife could exist. If an afterlife for humans did exist this would mean other animals with brains would too have to have an afterlife as they would too possess an afterlife.
Therefore I am presenting a reductio ad absurdum argument in the sense that it is impossible for there to be an afterlife as it would mean goats, cows and sheep’s alike would too have to an after life. What about people who die very young? How can they have an afterlife? Would they grow up in their current form? What about old people who lose their memory and their thoughts? Do they too have an afterlife? How is this possible? Where is the afterlife? Is it physical or is it spiritual?
I myself would hope there is an afterlife. I hate the idea of there being nothingness although there was nothingness for billions of years before my birth! So is this rational fear or innate fear? I believe that this fear is in our brains as in innate. This is because as a species we needed traits to survive. Just like today when domesticated cats will hide their faeces and will still fear direct eye contact. This behaviour in the wild would help the cat survive.
In conclusion I agree with the statement “It cannot be true that there is life after death, because there is no evidence for it.” On the grounds that there is no scientific evidence for an after life and also because the practical theory of an afterlife is next to impossibility.
