DJ Vlad asks Neil deGrasse Tyson a very compelling question about the existence of a soul in a human being.

To that, the renowned science commentator refers DJ Vlad to a German engineer who invented X-Rays in 1895 named W.C. Röntgen, before indicating that even when people tried to search for proof that a soul exited a person’s body before they died, no such evidence exists. From there, Neil explains that the foundation for the functionality of human beings is the electrical chemical synapses running through their brains.
