Why haven't all of us just given up hope and become extinct?

no matter what everyone dies. no one knows when, but it doesn't really matter does it. This is basic existentialism, but life feels good. We want to survive, and to flourish in what life offers. You have two questions here, your second one includes the premise that the universe will cease to exist. Now if that were the case we'd still try to live to the very end, because that is what humans do, that is what everything that lived on earth has done. The only reason to choose to end our own lives is if we decide survival is impossible or life isn't worth perhaps the pain or sadness it brings, or even lack of happiness.

It is very difficult to persuade yourself this, I believe, even though one may be suicidal the lens through which they is only one filter of the deeper reason to end existence, and either they fall deeper into the pit of that small lens, or they answer the question that there is more to life than just the one down that may haunt them.

Sort of like thinking if the world was all one Nazi Germany and the entire population was Jewish. Difficult to persuade everyone that everyone is not worth living.

In my opinion, the point to our existence is not spelled-out in the ideograms of the Bible, Qu ran, nor Torah. We may simply be buying time for our kind. Maybe the point in life for the majority of us is to simply carry on our species until the minority (the deeper thinkers, inventors, scientists, etc.) figure out what the ultimate point is.

It doesn't really even matter.

Only you can decide what would make your life better. I am an old dude that has seen much. One of the best things in my life has been the continual improvement that I have been able to achieve. I have, get, and still need a lot of help. I used to be a very bad person. I am a better person now, and I know that I will be yet better in the future, whatever it may bring. I will contribute to our world. I am a full-on member.

To have a better life, you have to set goals that are valuable, measurable, and achievable. The way to value these goals will depend on your personal life-long philosophy, which should and will, evolve as you grow as a person. For me it is to become a better human being and citizen of the world. Day by day. Year after year.

My personal philosophy is to be the best world citizen I can be, try to influence others to live the same way, and contribute to society in any way that I can. This includes being informed and up-to-date on the issues. Not because I will be rewarded in the end. Not because some religion tells me that I must do so to avoid hell, but because it is the only thing that makes sense.

I only really know myself and what I like. But I also know about feelings and emotions. They are tied to our attitude.

I have been working on my personal mental attitude for many years and have gotten a good hold on it. I choose to have a positive mental attitude and I almost always feel happy.

The greatest discovery of my generation is that we can alter our life simply by altering our attitude of mind. We cannot change our past. We cannot change the fact that people act in a certain way. We cannot change the inevitable. The only thing we can do is play on the one string we have, and that is our attitude.

The greatest day in your life and mine is when we take total responsibility for our attitudes. That's the day we truly grow up. Attitudes are a secret power working twenty-four hours a day, for good or bad. It is of paramount importance that we know how to harness and control this great force.

Our attitudes control our emotions. Our emotions control our perception. We control our attitudes.

Happiness is an attitude of mind, born of the simple determination to be happy under all outward circumstances. The happiest of people don't necessarily have the best of everything they just make the most of everything that comes their way

Start to develop your philosophy now and measure yourself against your old-self. Continuous improvement is the only way to a truly fulfilling life.

Love and peace to you, forever.

No, I will die someday but in the meantime I will enjoy each day.
