Man stands inside of old dark tunnel with shining sun

No one really knows what happens when we die, but one man's theory has got everyone talking. 

Samuel Murray posted his thoughts to Facebook this weekend, proposing that the light at the end of the tunnel is actually coming from a hospital room where we are born again.

Murray added that babies cry at birth because they remember everything from their past life, which they have now lost. He suggested that as we grow, we forget that past life, but patches of memory stay behind and cause deja vu.

While many people spent the day thinking about Murray's theory, plenty of others shot it down with the main complaint being that if it were true, the Earth's population would remain the same. 

Other people just think Samuel was high.
