Many doctors and scientists for a long time not only denied the existence of hell and heaven, but also completely excluded the possibility of an afterlife. But the testimony of eyewitnesses who experienced this condition and experienced clinical death drove scientists into a dead end. Tunnel and light, voices of loved ones and songs of angels... Which of all this is true? After all, questions of the afterlife worry almost everyone living on this earth. Some are afraid of death, while others are not, believing that it is similar to oblivion. A person thinks that he will close his eyes and fall asleep and never wake up again, and behind the veil of sleep there is only darkness without beginning and end. Someone thinks differently, believing that death is not the end, but only the beginning of a new path...Everyone born must die. This is the law. But modern science, following religion, comes to the conclusion: death is not the end, but rather a transition from one state to another. Scientific instruments record that there is something behind bodily death. But what? Let's try to figure it out by turning to science, religions and the testimonies of those who experienced clinical death.
