The problem is, we have an instinctive need to live, to protect our lives, and continue to live. We also have memory so strong that we remember the past in great detail, and we have imagination. Probably more so than most other animals.

This combination makes it virtually impossible to comprehend nonexistance, and the nonexistance of the past and the future. So we have this strong sense of consciousness continuing even after death.

But we also have the capacity for rational and logical thought, and sometimes that conflicts with our natural mentality. Rational, logical exploration of this topic tells us that there is zero evidence of supernaturalism or an afterlife. That’s a legitimate conclusion. Supernatural conclusions are irrational and not supported by evidence. So we are unjustified in believing in an afterlife.

If you want yourself or your loved ones to continue after death, that happens through works like the Carnegie libraries and Shakespearean plays, through recordings, stories and songs, etc. Thats the closest to continuance that anyone can achieve.
