Actually virtual particles are not particles at all They are little disturbances in the field...
A particle is a nice, regular ripple in a field, one that can travel smoothly and effortlessly through space, like a clear tone of a bell moving through the air. A “virtual particle”, generally, is a disturbance in a field that will never be found on its own, but instead is something that is caused by the presence of other particles, often of other fields.
The YouTube comments are hard to read on the video, it's nothing but hand waving away the data/everything these presenters said from these arm chair scientist/psychologist or long post on how there isn't life after death because we are biased and easily manipulated, we want there to be life after death so there can't be.
For an afterlife to exist, you might need particles and fields beyond the standard model. The big bang focuses everyone's attention away from pre-big bang mechanisms. Yeah, I think there is an afterlife, I think those particles and fields are available.
