So for these folks, the meaning of life must be death. I say this because if their lives continue in some way after death with consciousness, they will see clearly what it all means.
On the other hand, the question of the meaning of life today, or maybe tomorrow, could be that day by day, somehow, we might qualify for what our status might be after death. So for them, the meaning might be “each day.” It could be added that one should find out what is wanted for the best situation after death and then do it.
Of course, a person could not focus on anything connected with death and not be led to conclude that a better focus is about life rather than death.
Looking around at what life is about each day, it is hard to discount that life is full of other people. Yes, many are weird. Others will have opinions about us and whether our actions make sense. Perhaps even the weirdo may have an idea of how others treat them compared to how they treat others. This being the case, it works in favor of concluding that the meaning of life is in how we treat others.
